- A.
121%

- B.
321%

- C.
221%

- D.
300%

Answer: Option C

**Explanation** :

Amount invested on B, C, D and E in year 1

= 4.6 + 5.8 + 3.11 + 10.6 = 24.11

Amount invested on B, C, D and E in year 3

= 18.7 + 21.2 + 7.7 + 29.8 = 77.4

∴ Percentage increase $=\frac{77.4-24.11}{24.11}$ × 100 221%

**Direction: **Answer the questions based on the following information, which gives data about certain coffee producers in India.

**11. CAT 1996 LRDI | DI - Tables & Graphs**

What is the maximum production capacity (in '000 tonnes) of Lipton for coffee?

- A.
2.53

- B.
2.85

- C.
2.24

- D.
2.07

Answer: Option A

**Explanation** :

Lipton production is 1.64 (in ‘000 tonnes) which corresponds to 64.8% capacity. Maximum capacity will be 100%. For 64.8% it is 1.64 . ∴ For 100% it will be $\left(\frac{100}{64.8}\right)\times 1.64\approx \frac{100}{65}$ × 1.64 ≈ 2.53 (in ‘000 tonnes).

What percent of the total market share (by sales value) is controlled by ‘others’?

- A.
60%

- B.
32%

- C.
67%

- D.
insufficient data

Answer: Option B

**Explanation** :

Total sales of all brands = (31.15 + 26.75 + 15.25 + 17.45) = Rs. 90.6 crore

Total sales value of others = 132.8 – 90.6 = Rs. 42.2 crore

Required percentage = $\frac{42.2}{132.8}\times 100\approx \frac{42}{132}$ × 100 = 31.18 ≈ 32%

**Direction: **Answer the questions based on the following information.

Mulayam Software Co., before selling a package to its clients, follows the given schedule.

The number of people employed in each month is:

**16. CAT 1996 LRDI | DI - Tables & Graphs**

Due to overrun in ‘design’, the design stage took 3 months, i.e. months 3, 4 and 5. The number of people working on design in the fifth month was 5. Calculate the percentage change in the cost incurred in the fifth month. (Due to improvement in ‘coding’ technique, this stage was completed in months 6-8 only.)

- A.
225%

- B.
150%

- C.
275%

- D.
240%

Answer: Option B

**Explanation** :

Originally for the fifth month, 4 people were scheduled to do coding. This would have cost them (10000 × 4)

= Rs. 40,000. Now there are 5 people who are working on design in the fifth month.

The total cost for this would be (20000 × 5) = Rs.1,00,000.

Hence, percentage change in the cost incurred in the fifth month = $\frac{(10000040000)}{40000}\times $ 100 = 150%

Workspace:

**17. CAT 1996 LRDI | DI - Tables & Graphs**

With reference to the above question, what is the cost incurred in the new ‘coding’ stage? (Under the new technique, 4 people work in the sixth month and 5 in the eighth.)

- A.
Rs. 1,40,000

- B.
Rs. 1,50,000

- C.
Rs. 1,60,000

- D.
Rs. 1,70,000

Answer: Option A

**Explanation** :

As given in the previous question, it can be seen that the coding stage is now completed in 6th, 7th and 8th months.

Number of people employed in the 6th month is 4 and in the 8th month is 5. In the 7th month also there are 5 people employed (from previous data). Hence, if we were to combine these months, we find that the total cost incurred in the coding stage = (5 + 5 + 4) × 10000 = Rs.1,40,000.

Total investment in the two districts in 1996 = 3489.5 + 8352 ≈ 11840.

Required percentage = $\frac{(11840-10000)}{10000}\approx 18\%$

Workspace:

**22. CAT 1996 LRDI | DI - Tables & Graphs**

The investment in electricity and thermal energy in 1995 in these two districts formed what per cent of the total investment made in that year?

- A.
41%

- B.
47%

- C.
52%

- D.

Answer: Option B

**Explanation** :

Total investment in electricity and thermal energy in both the districts in 1995 = (815.2 + 632.4 + 2065.8 + 1232.7) = 4746.1.

Total investment made in that year = 2923.1 + 7081.6 = 10004.7 ≈ 10000

Hence, required percentage is $\frac{4746.1}{10,000}\approx 47\%$

- A.
Electricity

- B.
Chemical

- C.
Solar

- D.
Nuclear

Answer: Option B

**Explanation** :

Percentage increase in investment in electricity ≈ $\frac{300}{2070}$ = 14%. Percentage increase in investment in chemical ≈ $\frac{(986.4-745.3)}{745.31}\times 100\approx \frac{240}{745}\approx 32\%.$

Percentage increase in investment in solar $=\frac{428.6}{1792.1}\approx \frac{430}{1792}\approx 23\%$

Percentage increase in investment in nuclear $=\frac{507.8}{1674.3}\approx \frac{500}{1670}\approx 29\%$ Clearly percentage increase in investment in chemical is the highest.

**45. CAT 1996 LRDI | LR - Cubes**

A cube of side 12 cm is painted red on all the faces and then cut into smaller cubes, each of side 3 cm. What is the total number of smaller cubes having none of their faces painted?

- A.
16

- B.
8

- C.
12

- D.
24

Answer: Option B

**Explanation** :

Since each side of the smaller cube is 3 cm, it can be figured out that each face of the original cube is divided into 4 parts, or in other words, the original cube is divided into 64 smaller cubes. For a smaller cube to have none of its sides painted, it should not be a part of the face of the original cube (i.e. none of its faces should be exposed).

We can find at the centre of the original cube there are (2 × 2 × 2) = 8 such cubes.

**Hint:**

****Students please note that the answer can only be a cube of some integer. The only cube among the answer choices is (2)^{3} = 8.

**46. CAT 1996 LRDI | LR - Clocks**

In a watch, the minute hand crosses the hour hand for the third time exactly after every 3 hr 18 min and 15 s of watch time. What is the time gained or lost by this watch in one day?

- A.
14 min 10 s lost

- B.
13 min 50 s lost

- C.
13 min 20 s gained

- D.
14 min 40 s gained

Answer: Option B

**Explanation** :

In a watch that is running correct, the minute hand should cross the hour hand once in every 65 + $\frac{5}{11}$ min. So they should ideally cross three times once in $3\times \left(\frac{720}{11}\right)=\frac{2060}{11}$ min = 196.36 min. But in the watch under consideration they meet after every 3 hr, 18 min and 15 s, i.e. (3 × 60 + 18 + $\frac{15}{60}$) = $\frac{793}{4}$ min = 198.25 min. In other words, our watch is actually losing time (as it is slower than the normal watch). Hence, when our watch elapsed 198.25 min, it actually should have elapsed 196.36 min. So in a day, when our watch will elapse (60 × 24) = 1440, it should actually elapse $\left(1440\times \frac{196.36}{198.25}\right)$ = 1426. 27. Hence, the amount of time lost by our watch in one day = (1440 – 1426.27) = 13.73, i.e. 13 min and 50 s (approximately).
