Let,

A = The breakfast doesn't have eggs

B = I will not go for a walk and will not have lunch.

From the logical deductions,

AB = ~B~A

Also, and is replaced by or and vice versa.

So,

~A = The breakfast has eggs.

~B = I will go for a walk or will have lunch.

vii. Kripa is the least qualified amongst the daughters.

**7. IIFT 2015 LRDI | LR - Selection & Distribution**

Who is the third tallest starting in decreasing order of height?

- A.
Kamla

- B.
Kamlesh

- C.
Kriti

- D.
Kranti

Answer: Option B

**Explanation** :

Let us rank their heights and their qualification on a scale from 1 to 6.

Rank 1 is the tallest and the most qualified and Rank 6 is the shortest and the least qualified.

Kamla is not the tallest. So Kamla's height can be any rank from 2 to 5.

Kripa is the least qualified amongst the daughters. So Kripa_{Q }_{= }6 (sub-script Q and H denote rank for qualification and height respectively).

From st iv, v and vi, we conclude that

Kamla_{H} > Kamlesh_{H} > Kriti_{H} > Kalpana_{H }> Kranti_{H}

But Kamla is not be the tallest. Therefore Kripa is the tallest and Kamla is the 2^{nd }tallest and the order follows as shown above.

From St ii, Kranti_{Q }= 1.

From St iii and from st vi, we conclude that

Kalpana_{Q} > Kamlesh_{Q} >Kriti_{Q} >Kamla_{Q}

Therefore on the basis of the qualification,

Kalpana's rank is 2, Kamlesh's rank is 3, Kriti's rank is 4 and Kamla's rank is 5.

The following table can be regarding their height and qualification:

Decreasing order of height are the ranks starting from 1 upto 6.

Third tallest amongst all is Kamlesh

- A.
2

- B.
4

- C.
3

- D.
5

Answer: Option B

**Explanation** :

From the figure, Cargo can go from city P to city U in only one possible way i.e. P-Q-R-T-V-U. Going through this path, the cargo will have to pass through 4 cities.

Hence, option 2.

Workspace:

**20. IIFT 2015 LRDI | DI - Routes & Networks**

To move cargo from City P to City U, which of the following statements will minimise the number of cities to be crossed in transit?

- A.
Connect cities U to R with a two way connection

- B.
Connect cities P to S with a one way connection from cities S to P

- C.
Connect cities U to Q with a two way connection

- D.
Connect cities R to V with a two way connection

Answer: Option C

**Explanation** :

Consider option A. The path is P-Q-R-U. We have to cross 2 intermediate cities in it.

Consider option B. If we connect cities from P to S with a one way connection from cities S to P. The path formed will be P-Q-R-T-V-U. It becomes a longer path than option A.

Using option C, the path formed is the shortest path. The path formed is P-Q-U. This smaller than that in option A.

Consider option D. The path formed using option D is longer compared to the path formed using option C. Hence options A, B, and D are eliminated.

Hence, option 3.

Which type of WAC has performed the second best in Half Yearly Sales Performance?

- A.
½ Ton

- B.
1 Ton

- C.
1½ Ton

- D.
2 Ton

Answer: Option C

**Explanation** :

Sales for various WAC types from Oct-14 to Mar-15:

Two ton: 0.25 × 1300 + 0.31(1340 + 1350) + 0.25(3928) = 2141

One & Half ton: 0.33 × 1300 + 0.19(1340 + 1350) + 0.33(3928) = 2236

One ton: 0.12 × 1300 + 0.34(1340 + 1350) + 0.26(3928) = 2092

One & Half ton: 0.3 × 1300 + 0.16(1340 + 1350) + 0.16(3928) = 1449

Referring to previous solution, the sales for various WAC types from Apr-14 to Sep-14:

Two ton: 3950 – 2141 = 1809

One & Half ton: 4056 – 2236 = 1820

One ton: 3376 – 2092 = 1284

One & Half ton: 4226 – 1449 = 2777

Half yearly sales performance for various types is:

$2ton=\frac{\left({\displaystyle \frac{2141}{6}}\right)-\left({\displaystyle \frac{1809}{6}}\right)}{\left({\displaystyle \frac{1809}{6}}\right)}$

$=\frac{2141-1809}{1809}\approx 0.18$

$1\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.ton=\frac{2236-1820}{1820}\approx 0.23$

1 ton $=\frac{2092-1284}{1284}\approx 0.63$

$\frac{1}{2}ton=\frac{1449-2777}{2777}\approx -0.48$

Thus, second best performance in Half Yearly Sales Performance is of 1½ ton WACs.

Hence, option 3.

Sales volatility of 2 ton WAC

$=\frac{419-253}{329}\approx 0.5$

Sales volatility of 1^{1}/_{2} ton WAC

$=\frac{439-241}{338}\approx 0.59$

Sales volatility of 1 ton WAC

$=\frac{459-153}{281}\approx 1.09$

Sales volatility of^{ 1}/_{2} ton WAC

$=\frac{609-207}{352}\approx 1.14$

Thus, 2 ton of WAC has the least Sales Volatility.

**Read the following information, graph and table and answer the questions that follow.**

Ellen Inc. is a Mumbai based company which sells five products branded as A, B, C, D and E in India. Anita looks after entire sales of North India working from regional office in Delhi. She was preparing for annual review meeting scheduled next day in Mumbai. She was attempting to analyse sales in North India for the seven year period from 2009 to 2015. She first calculated average sales in rupees of all the five brands and constructed a table exhibiting the difference between average sales of each pair of brands as shown in the following table:

**Difference Between Average Sales of Products for the 7 year period 2009-15 in Rs Crores**

After taking a print out of the above table, she attempted to look at the trend of sales and plotted a graph in MS Excel. Later she took a print out of the graph and left for a meeting. While on her way she figured out that due to some printer cartridge problem sales of Product A in 2013, Product C in 2010, and Product D in 2012 were not visible in the graph as reproduced below. Anita had to make some quick calculations to arrive at the information outlined in the following questions:

**26. IIFT 2015 LRDI | DI - Tables & Graphs**

What are the sales of Product A in 2013, Product C in 2010 and Product D in 2012?

- A.
Rs. 550 Crores, Rs. 800 Crores and Rs. 500 Crores

- B.
Rs. 500 Crores, Rs. 700 Crores and Rs. 600 Crores

- C.
Rs. 500 Crores, Rs. 800 Crores and Rs. 600 Crores

- D.
Rs. 4000 Crores, Rs. 800 Crores and Rs. 600 Crores

Answer: Option C

**Explanation** :

The first table gives the difference between the average sales of various products over seven years.

e.g. A – B = 214.29 crores

Hence, total difference between A and B over the seven year period is:

A – B = 214.29 × 7 = 1500 crores

Similarly,

C – A = 900 cr, A – D = 1000 cr, A – E = 300 cr, C – B = 2400 cr, D – B = 500 cr, E – B

= 1200 cr, C – D = 1900 cr, C – E = 1200 cr,

E – D = 700 cr

Let the sales of A in 2013 be *a*(‘000s), C in 2010 be *c*(‘000s) and D in 2012 be *d*(‘000s).

The total sales, by volume, of each product are:

A = (6800 + *a*) × 10^{3}

B = 5800 × 10^{3}

C = (7400 + *c*) × 10^{3}

D = (5700 + *d*) × 10^{3}

E = 7000 × 10^{3}

Hence, difference between number of units sold of B and E = 1200 × 10^{3}

Assuming that each product is sold at the same cost in each year,

Cost per product = (1200 cr)/(1200 thousand) = (1200 × 10^{7})/ (1200 × 10^{3})

= 10000

∴ Total sales of B over the given period = 5800 × 10^{3 }× 10000 = 5800 × 10^{7 }= 5800 crores

Similarly, total sales of E over the given period = 7000 × 10^{3 }× 10000 = 7000 × 10^{7 }= 7000 crores

Using these values in the equations above, A = 7300 crores, C = 8200 crores, D

= 6300 crores

Also, total sales of A = (6800 + *a*) × 10^{3 }× 10000 = (6800 + *a*) × 10^{7}

= (6800 + *a*) crores

Comparing this value with 7300 crores (found as total sales of A earlier),

*a* = 7300 – 6800 = 500 crores

Similarly, *c* = 800 crores and *d*

= 600 crores

Hence, option 3.

Annual sales average of all products is the least in which year?

- A.
2010

- B.
2011

- C.
2012

- D.
2013

Answer: Option B

**Explanation** :

Because the cost per product is assumed to be the same for each product for each year, the average sales (or total sales) for any year across products can be found on the basis of units sold itself.

i.e., the year with highest units sold will also have highest average annuals sales.

2010: 500 + 600 + c + 1200 + 1600

= 3900 + c = 3900 + 800 = 4700

2011: 800 + 600 + 1400 + 1100 + 300 = 4200

2012: 1200 + 1000 + 1500 + d + 200

= 3900 + d = 3900 + 600 = 4500

2013: a + 1000 + 800 + 100 + 2000 = a + 3900 = 4400

Thus, the minimum sales are in 2011.

Hence, option 2.

Which product has the least average sales for the seven year period 2009-15?

- A.
Product A

- B.
Product B

- C.
Product D

- D.
Product E

Answer: Option B

**Explanation** :

The first table gives the difference between the average sales of various products over seven years.

e.g. A – B = 214.29 crores

Hence, total difference between A and B over the seven year period is:

A – B = 214.29 × 7 = 1500 crores

Similarly,

C – A = 900 cr, A – D = 1000 cr, A – E = 300 cr, C – B = 2400 cr, D – B = 500 cr, E – B

= 1200 cr, C – D = 1900 cr, C – E = 1200 cr,

E – D = 700 cr

Let the sales of A in 2013 be *a*(‘000s), C in 2010 be *c*(‘000s) and D in 2012 be *d*(‘000s).

The total sales, by volume, of each product are:

A = (6800 + *a*) × 10^{3}

B = 5800 × 10^{3}

C = (7400 + *c*) × 10^{3}

D = (5700 + *d*) × 10^{3}

E = 7000 × 10^{3}

Hence, difference between number of units sold of B and E = 1200 × 10^{3}

Assuming that each product is sold at the same cost in each year,

Cost per product = (1200 cr)/(1200 thousand) = (1200 × 10^{7})/ (1200 × 10^{3})

= 10000

∴ Total sales of B over the given period = 5800 × 10^{3 }× 10000 = 5800 × 10^{7 }= 5800 crores

Similarly, total sales of E over the given period = 7000 × 10^{3 }× 10000 = 7000 × 10^{7 }= 7000 crores

Using these values in the equations above, A = 7300 crores, C = 8200 crores, D

= 6300 crores

Also, total sales of A = (6800 + *a*) × 10^{3 }× 10000 = (6800 + *a*) × 10^{7}

= (6800 + *a*) crores

The product having the least total sales over the given period will also have the least average.

Hence, this product is B, with total sales of Rs. 5800 crores.

Hence, option 2.

then the YoY growth of combined sales of all products has suffered maximum decline in which year?

- A.
2010

- B.
2011

- C.
2013

- D.
2015

Answer: Option C

**Explanation** :

The first table gives the difference between the average sales of various products over seven years.

e.g. A – B = 214.29 crores

Hence, total difference between A and B over the seven year period is:

A – B = 214.29 × 7 = 1500 crores

Similarly,

C – A = 900 cr, A – D = 1000 cr, A – E = 300 cr, C – B = 2400 cr, D – B = 500 cr, E – B

= 1200 cr, C – D = 1900 cr, C – E = 1200 cr,

E – D = 700 cr

Let the sales of A in 2013 be *a*(‘000s), C in 2010 be *c*(‘000s) and D in 2012 be *d*(‘000s).

The total sales, by volume, of each product are:

A = (6800 + *a*) × 10^{3}

B = 5800 × 10^{3}

C = (7400 + *c*) × 10^{3}

D = (5700 + *d*) × 10^{3}

E = 7000 × 10^{3}

Hence, difference between number of units sold of B and E = 1200 × 10^{3}

Assuming that each product is sold at the same cost in each year,

Cost per product = (1200 cr)/(1200 thousand) = (1200 × 10^{7})/ (1200 × 10^{3})

= 10000

∴ Total sales of B over the given period = 5800 × 10^{3 }× 10000 = 5800 × 10^{7 }= 5800 crores

Similarly, total sales of E over the given period = 7000 × 10^{3 }× 10000 = 7000 × 10^{7 }= 7000 crores

Using these values in the equations above, A = 7300 crores, C = 8200 crores, D

= 6300 crores

Also, total sales of A = (6800 + *a*) × 10^{3 }× 10000 = (6800 + *a*) × 10^{7}

= (6800 + *a*) crores

The same concept can be used for this question.

The values for 2010, 2011, 2012 and 2013 were already known.

Based on the options, find the values for 2009, 2014 and 2015.

2009: 1200 + 300 + 1500 + 600 + 1300

= 4900

2014: 1800 + 700 + 1200 + 900 + 1300

= 5900

2015: 1300 + 1600 + 1000 + 1800 + 300

= 6000

Since the sales increase from 2014 to 2015, option 4 can be directly eliminates as we need to find % decline.

For the other three values, it can be observed that the maximum % decline is in 2011.

Hence, option 3.
