Answer: Option A

Join our Telegram Group for CAT Preparation.

**Explanation** :

Man-hours spent in coding = offshore coding + onsite coding = 410 + 100 = 510

Now, total man-hours spent in offshore design and offshore coding = 100 + 410 = 510

Hence, option (a).

Workspace:

**10. CAT 2001 LRDI | DI - Tables & Graphs**

Roughly what percentage of the total work is carried out onsite?

- A.
40 percent

- B.
20 percent

- C.
30 percent

- D.
50 percent

Answer: Option C

Join our Telegram Group for CAT Preparation.

**Explanation** :

Total man-hours spent on offshore work = 100 + 410 + 290 = 800

And total man-hours spent on onsite work = 90 + 100 + 150 = 340

∴ Percentage onsite work = 340/(800 + 340) ≈ 30%

Hence, option (c).

Workspace:

**11. CAT 2001 LRDI | DI - Tables & Graphs**

The total effort in man-hours spent onsite is nearest to which of the following?

- A.
The sum of the estimated and actual effort for offshore design

- B.
The estimated man-hours of offshore coding

- C.
The actual man-hours of offshore testing

- D.
Half of the man-hours of estimated offshore coding

Answer: Option C

Join our Telegram Group for CAT Preparation.

**Explanation** :

Total man-hours spent on onsite work = 90 + 100 + 150 = 340

Sum of the estimated and actual effort for offshore design = 100 + 100 = 200

Estimated man-hours of offshore coding = 410

Actual man-hours of offshore testing = 300

Half of the man-hours of estimated offshore coding = 205

∴ Total man-hours spent on onsite work is more closer to actual man-hours of offshore testing.

Hence, option (c).

Workspace:

**12. CAT 2001 LRDI | DI - Tables & Graphs**

If the total working hours were 100, which of the following tasks will account for approximately 50 hours?

- A.
Coding

- B.
Design

- C.
Offshore testing

- D.
Offshore testing plus design

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Explanation** :

Using the data from the previous question.

Total amount of work = 800 + 340 = 1140

Total coding man-hours = 410 + 100 = 510

Total design man-hours = 90 + 100 = 190

Total offshore testing man-hours = 290

Total offshore testing plus design man-hours = 290 + 190 = 480

50% of 1140 = 570

510 is more closer to 570.

Hence, option (a).

Workspace:

**13. CAT 2001 LRDI | DI - Tables & Graphs**

If 50 percent of the offshore work were to be carried out onsite, with the distribution of effort between the tasks remaining the same, the proportion of testing carried out offshore would be

- A.
40 percent

- B.
30 percent

- C.
50 percent

- D.
70 percent

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Explanation** :

Man-hours required for testing offshore = 290

50% of this is now carried out onsite.

∴ Man-hours for testing offshore = 290 − 145 = 145

And man-hours for testing onsite = 150 + 145 = 295

Total man-hours of testing = 145 + 295 = 440

∴ Required percentage = (145 × 100)/440 ≈ 33%

Hence, option (b).

**Answer the following question based on the information given below.**

The following sketch shows the pipelines carrying material from one location to another. Each location has a demand for material. The demand at Vaishali is 400, at Jyotishmati is 400, at Panchal is 700, and at Vidisha is 200. Each arrow indicates the direction of material flow through the pipeline. The flow from Vaishali to Jyotishmati is 300. The quantity of material flow is such that the demands at all these locations are exactly met. The capacity of each pipeline is 1000.

**15. CAT 2001 LRDI | DI - Routes & Networks**

The quantity moved from Avanti to Vidisha is

- A.
200

- B.
800

- C.
700

- D.
1000

Answer: Option D

Join our Telegram Group for CAT Preparation.

**Explanation** :

Demand at Panchal = 700

∴ Quantity of material flowing in the pipeline from Jyotishmati to Panchal = 700

Also, Flow from Vaishali to Jyotishmati + Flow from Vidisha to Jyotishmati = Demand at Jyotishmati + Demand at Panchal

∴ 300 + Flow from Vidisha to Jyotishmati = 400 + 700 = 1100

∴ Flow from Vidisha to Jyotishmati = 1100 − 300 = 800

Now, Flow from Avanti to Vaishali = Demand at Vaishali + Flow from Vaishali to Jyotishmati

∴ Flow from Avanti to Vaishali = 300 + 400 = 700

Also, Flow from Avanti to Vidisha = Demand at Vidisha + Flow from Vidisha to Jyotishmati

∴ Flow from Avanti to Vidisha = 200 + 800 = 1000

The diagram above shows the flow of the material in the pipelines and the demand at the respective points.

∴ Quantity of material moved from Avanti to Vidisha = 1000

Hence, option (d).

Answer: Option D

Join our Telegram Group for CAT Preparation.

**Explanation** :

From the flow diagram, we have,

Each pipeline has a capacity of 1000 and the flow in the Avanti-Vaishali pipeline is 700.

∴ Free capacity available = 1000 − 700 = 300

Hence, option (d).

Workspace:

On her walk through the park, Hansa collected 50 coloured leaves, all either maple or oak. She sorted them by category when she got home, and found the following:

A. The number of red oak leaves with spots is even and positive.

B. The number of red oak leaves without any spot equals the number of red maple leaves without spots.

C. All non-red oak leaves have spots, and there are five times as many of them as there are red spotted oak leaves.

D. There are no spotted maple leaves that are not red.

E. There are exactly 6 red spotted maple leaves.

F. There are exactly 22 maple leaves that are neither spotted nor red.

How many oak leaves did she collect?

- A.
22

- B.

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Explanation** :

Let the number of red but not spotted oak leaves be ‘x’ and number of red spotted oak leaves be ‘y’.

From the given conditions, we get the following tabulated table.

But, 6 + x + 22 + y + x + 5y = 50

∴ 28 + 2x + 6y = 50

∴ x + 3y = 11

∵ Red spotted oak leaves has to be positive and even.

∴ y = 2

∴ x = 11 − 3 × 2 = 5

∴ Number of Oak leaves = x + y + 5y = 5 + 6 × 2 = 17

Hence, option (b).

**Explanation** :

As, O, P, Q, R are on motorcycle M1, M2, M3, M4 respectively. Hence we get,

Now, A is with Q and G is with Q hence A is with G on motorcycle M3.

And F is on M1 and E is on M2.

P is with D hence D is with E.

As B cannot go with R hence he has to go with F on motorcycle M1.

Hence C and H go together on motorcycle M4.

Hence we get,

I have a total of Rs. 1,000. Item A costs Rs. 110, item B costs Rs. 90, item C costs Rs. 70, item D costs Rs. 40 and item E costs Rs. 45. For every item D that I purchase, I must also buy two of item B. For every item A, I must buy one of item C. For every item E, I must also buy two of item D and one of item B. For every item purchased I earn 1000 points and for every rupee not spent I earn a penalty of 1500 points. My objective is to maximise to points I earn. What is the number of items that I must purchase to maximise my points?

- A.
13

- B.
14

- C.
15

- D.

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Explanation** :

To maximise the points, I should spent the entire amount and should get as many items as possible.

∴ I can maximize my points by purchasing 13C’s and 1B as there is no condition on the purchase of C and B.

∴ Total cost = 13 × 70 + 90 = 910 + 90 =1000

∵ The entire amount has been spent, there is no penalty.

∴ Number of points earned = 14 × 1000 = 14000

Hence, option (b).

What is the costliest item the Deepak could buy with his own money?

- A.
A shirt

- B.
A shawl

A jacket

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Explanation** :

Let Ashok, Bashir, Chirag and Deepak have amounts Rs. A, Rs. B, Rs. C and Rs. D respectively. From the data given in the question, we have following equations.

A < 3B ... (i)

C > B ... (ii)

D = C − B ... (iii)

A = 3D ... (iv)

Chirag borrows Rs. 300 from Ashok and buys a jacket worth Rs. 1000.

∴ C ≥ 700 ... (v)

Bashir buys a sweater after borrowing Rs. 100 from Ashok and left with no money.

∴ B = 500 ... (vi)

Ashok buys 3 shirts (costing Rs. 600 in total) with Rs. A − 300 − 100

∴ A ≥ 1000

From (i) and (vi), we get,

A < 1500

∴ 1000 ≤ A < 1500 ... (vii)

From equation (iv) and (vii), we get,

333 < D < 500

∴ Deepak could buy a shawl worth Rs. 400.

Hence, option (b).

In a "keep-fit" gymnasium class there are fifteen females enrolled in a weight-loss program. They all have been grouped in any one of the five weight-groups W1, W2, W3, W4, or W5. One instructor is assigned to one weight-group only. Sonali, Shalini, Shubhra, and Shahira belong to the same weight-group. Sonali and Rupa are in one weight-group, Rupali and Renuka are also in one weight-group. Rupa, Radha, Renuka, Ruchika and Ritu belong to different weight-groups. Somya cannot be with Ritu, and Tara cannot be with Radha. Komal cannot be with Radha, Somya, or Ritu. Shahira is in W1 and Somya is in W4 with Ruchika. Sweta and Jyotika cannot be with Rupali, but are in a weight-group with total membership of four. No weight-group can have more than five or less than one member.

- A.
Babita

- B.
Elina

- C.
Chandrika

- D.
Deepika

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Explanation** :

Based on the information provided, the data can be summarized as follows.

From the first two statements, we get that Sonali, Shalini, Shubhra, Shahira and Rupa are in the same weight group with a group size of 5.

It is given that Rupa, Radha, Renuka, Ruchika and Ritu belong to different weight-groups.

∴ There are 4 groups (i.e. of Radha, Renuka, Ruchika and Ritu) remaining.

∴ In the group along with Ruchika and Somya, there cannot be Radha, Renuka and Ritu, thus forming a group of 2.

Also, Komal cannot be with Radha, Ritu and Somya (Ruchika) and Rupa.

∴ She has go with Rupali and Renuka, thus forming a group of size 3.

If W1, W2, W3, W4 and W5 represent weight groups in the descending order of the group size then Sweta and Jyotika must contain Ritu and Tara as their group members as Somya and Ruchika belong to W4 thus forming a group of 4.

Otherwise Sweta and Jyotika can be either with Ritu and Tara or with Somya and Ruchika, but in both the cases Radha is alone and doesnot have any other member in the group.

∴ Elina is the instructor of Radha.

Hence, option (b)

**Answer the following question based on the information given below.**

A and B are two sets (e.g. A = mothers, B = women). The elements that could belong to both the sets (e.g. women who are mothers) is given by the set C = A.B. The elements which could belong to either A or B, or both, is indicated by the set D = A ∪ B. A set that does not contain any elements is known as a null set, represented by ϕ (for example, if none of the women in the set B is a mother, they C = A.B is a null set, or C = ϕ).

Let 'V' signify the set of all vertebrates; 'M' the set of all mammals; 'D' dogs; 'F' fish; 'A' Alsatian and 'P', a dog named Pluto.

**Explanation** :

A normal year has 52 weeks and 1extra day.

∴ 365 = 52 × 7 + 1

A leap year has 52 weeks and 2 extra days.

∴ 366 = 52 × 7 + 2

There are 30 extra days between 1971 and 2001.

In this period there were 8 leap years, therefore another 8 extra days.

∴ 38 = 7 × 5 + 3

∴ We are left with 3 extra days.

If 9/12/2001 is a Sunday, then 12/12/1971 was a Sunday and 9/12/1971 was a Thursday.

[3 days before Sunday is Thursday since we are going back in time.]

Hence, option (d).
