Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 1

### Find the total number of balls kept in the first row of column 3 and the third row of column 2.

Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 1

For Row 1:
For Row 1 & Column 1:
⇒ (* + 12)/2 = 9
⇒ * = 6; then, the number of red balls kept in the three boxes is (6, 9, 12).
For Row 1 & Column 2:
⇒ (2 + 10)/2 = 6
⇒ * = 6; then, the number of red balls kept in the three boxes is (2, 6, 10)
For Row 1 & Column 3:
⇒ (4 + *)/2 = 6
⇒ * = 8; then, the number of red ball kept in the three boxes is (4, 6, 8).

For Row 2:
(a, b) is the solution of x2 – 9x + 20 = 0.
⇒ x– 4x – 5x + 20 = 0
⇒ (x – 4)(x – 5) = 0
⇒ x = 4, 5
So, a = 4, b = 5
(c, d) is the solution of x2 – 11x + 24 = 0.
⇒ x2 – 3x – 8x + 24 = 0
⇒ (x – 3)(x – 8) = 0
⇒ x = 3, 8
So, c = 3, d = 8
(e, f) is the solution of x2 – 13x + 40 = 0.
⇒ x2 – 5x – 8x + 40 = 0
⇒ (x – 5)(x – 8) = 0
⇒ x = 5, 8
So, e = 5, f = 8

For Row 3:
Total number of balls in the boxes of column 1 in row 1, row 2 and row 3 = (6 + 9 + 12) + (4 + 5) + (r + r + r) = 36 + 3r
Then, probability that the ball is black = (r + r + r)/(36 + 3r) = 1/5
⇒ 15r = 36 + 3r
⇒ 12r = 36
⇒ r = 36/12
⇒ r = 3
∴ The number of black balls in the boxes of row 3 of column 1 is (3, 3, 3).
Total number of balls in the boxes of column 3 in row 1, row 2 and row 3 = (4 + 6 + 8) + (5 + 8) + (q + q + q - 1) = 30 + 3q
Then, probability that the ball is black = (3q - 1)/(30 + 3q) = 11/42
⇒ 126q – 42 = 330 + 33q
⇒ 93q = 372
⇒ q = 4
∴ The number of black balls in the boxes of row 3 in column 3 is (4, 3, 4).
According to the given directions:
Total number of balls kept in row 3 in column 1, column 2 and column 3 = (3 + 3 + 3) + (p + p + 1 + p + 1) + (4 + 3 + 4) = 25
⇒ (3p + 22) = 25
⇒ 3p = 3
⇒ p = 1
∴ Number of black balls in row 3 of column 2 = (1, 2, 2)

Now, arranging all data in one table:

According to the question:
Required sum = (4 + 6 + 8) + (1 + 2 + 2) = 23

Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 2

### Find the ratio of the total number of green balls to the total number of black balls.

Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 2

For Row 1:
For Row 1 & Column 1:
⇒ (* + 12)/2 = 9
⇒ * = 6; then, the number of red balls kept in the three boxes is (6, 9, 12).
For Row 1 & Column 2:
⇒ (2 + 10)/2 = 6
⇒ * = 6; then, the number of red balls kept in the three boxes is (2, 6, 10)
For Row 1 & Column 3:
⇒ (4 + *)/2 = 6
⇒ * = 8; then, the number of red ball kept in the three boxes is (4, 6, 8).

For Row 2:
(a, b) is the solution of x2 – 9x + 20 = 0.
⇒ x– 4x – 5x + 20 = 0
⇒ (x – 4)(x – 5) = 0
⇒ x = 4, 5
So, a = 4, b = 5
(c, d) is the solution of x2 – 11x + 24 = 0.
⇒ x2 – 3x – 8x + 24 = 0
⇒ (x – 3)(x – 8) = 0
⇒ x = 3, 8
So, c = 3, d = 8
(e, f) is the solution of x2 – 13x + 40 = 0.
⇒ x2 – 5x – 8x + 40 = 0
⇒ (x – 5)(x – 8) = 0
⇒ x = 5, 8
So, e = 5, f = 8

For Row 3:
Total number of balls in the boxes of column 1 in row 1, row 2 and row 3 = (6 + 9 + 12) + (4 + 5) + (r + r + r) = 36 + 3r
Then, probability that the ball is black = (r + r + r)/(36 + 3r) = 1/5
⇒ 15r = 36 + 3r
⇒ 12r = 36
⇒ r = 36/12
⇒ r = 3
∴ The number of black balls in the boxes of row 3 of column 1 is (3, 3, 3).
Total number of balls in the boxes of column 3 in row 1, row 2 and row 3 = (4 + 6 + 8) + (5 + 8) + (q + q + q - 1) = 30 + 3q
Then, probability that the ball is black = (3q - 1)/(30 + 3q) = 11/42
⇒ 126q – 42 = 330 + 33q
⇒ 93q = 372
⇒ q = 4
∴ The number of black balls in the boxes of row 3 in column 3 is (4, 3, 4).
According to the given directions:
Total number of balls kept in row 3 in column 1, column 2 and column 3 = (3 + 3 + 3) + (p + p + 1 + p + 1) + (4 + 3 + 4) = 25
⇒ (3p + 22) = 25
⇒ 3p = 3
⇒ p = 1
∴ Number of black balls in row 3 of column 2 = (1, 2, 2)

Now, arranging all data in one table:

Total number of green balls = (4 + 5) + (3 + 8) + (5 + 8) = 33
Total number of black balls = (3 + 3 + 3 + 1 + 2 + 2 + 4 + 3 + 4) = 25
∴ Required ratio = 33 : 25
Therefore, option 1 is the correct answer.

⇒ * = 8; then, the number of red ball kept in the three boxes is (4, 6, 8).

For Row 2:
(a, b) is the solution of x2 – 9x + 20 = 0.
⇒ x– 4x – 5x + 20 = 0
⇒ (x – 4)(x – 5) = 0
⇒ x = 4, 5
So, a = 4, b = 5
(c, d) is the solution of x2 – 11x + 24 = 0.
⇒ x2 – 3x – 8x + 24 = 0
⇒ (x – 3)(x – 8) = 0
⇒ x = 3, 8
So, c = 3, d = 8
(e, f) is the solution of x2 – 13x + 40 = 0.
⇒ x2 – 5x – 8x + 40 = 0
⇒ (x – 5)(x – 8) = 0

So, e = 5, f = 8

For Row 3:
Total number of balls in the boxes of column 1 in row 1, row 2 and row 3 = (6 + 9 + 12) + (4 + 5) + (r + r + r) = 36 + 3r
Then, probability that the ball is black = (r + r + r)/(36 + 3r) = 1/5
⇒ 15r = 36 + 3r
⇒ 12r = 36
⇒ r = 36/12
⇒ r = 3
∴ The number of black balls in the boxes of row 3 of column 1 is (3, 3, 3).
Total number of balls in the boxes of column 3 in row 1, row 2 and row 3 = (4 + 6 + 8) + (5 + 8) + (q + q + q - 1) = 30 + 3q
Then, probability that the ball is black = (3q - 1)/(30 + 3q) = 11/42
⇒ 126q – 42 = 330 + 33q
⇒ 93q = 372
⇒ q = 4
∴ The number of black balls in the boxes of row 3 in column 3 is (4, 3, 4).
According to the given directions:
Total number of balls kept in row 3 in column 1, column 2 and column 3 = (3 + 3 + 3) + (p + p + 1 + p + 1) + (4 + 3 + 4) = 25
⇒ (3p + 22) = 25
⇒ 3p = 3
⇒ p = 1
∴ Number of black balls in row 3 of column 2 = (1, 2, 2)

Total number of balls in the boxes of column 1 in row 1, row 2 and row 3 = (6 + 9 + 12) + (4 + 5) + (r + r + r) = 36 + 3r
Then, probability that the ball is black = (r + r + r)/(36 + 3r) = 1/5
⇒ 15r = 36 + 3r
⇒ 12r = 36
⇒ r = 36/12
⇒ r = 3
∴ The number of black balls in the boxes of row 3 of column 1 is (3, 3, 3).
Total number of balls in the boxes of column 3 in row 1, row 2 and row 3 = (4 + 6 + 8) + (5 + 8) + (q + q + q - 1) = 30 + 3q
Then, probability that the ball is black = (3q - 1)/(30 + 3q) = 11/42
⇒ 126q – 42 = 330 + 33q
⇒ 93q = 372
⇒ q = 4
∴ The number of black balls in the boxes of row 3 in column 3 is (4, 3, 4).
According to the given directions:
Total number of balls kept in row 3 in column 1, column 2 and column 3 = (3 + 3 + 3) + (p + p + 1 + p + 1) + (4 + 3 + 4) = 25

As per the information given in (d), it can be concluded that Richard must have taken a copy of 10 sheets more than that of Harry (who went to the shop on Friday). Hence, Richard must have printed 30 sheets. Moreover, from (c), Jacob must have taken a copy of 40 sheets. Furthermore, Jacob must have visited the shop on Thursday as evident from (f). Neil must have printed 50 sheets and went to the shop on Wednesday.
Since Jacob went on Thursday, the friend who visited the shop on Tuesday (Patrick) must have made an assignment on Economics (as evident from (a)). Richard did not made the assignment on Ecology (as evident from (d)). Hence, Neil must have made the assignment on Ecology and Richard must have covered the Chemistry.

The table below presents this information:

Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 15

The difference between the average daily number of sheets printed in the first three days of the week and the last two days of the week is _____. Key in the value.

Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 15

Richard made an assignment on Chemistry.
An aspect about each of the five friends is clear from (b). It is evident that a friend who made an assignment on Biology didn't visit the shop on Monday and Tuesday.
Also, from (e), Harry went to the shop after the friend who made the assignment on Biology. Therefore, the friend who made an assignment on Biology would have visited on either Wednesday or Thursday. However, Harry would have visited the shop on either Thursday or Friday.
Among the five friends, as mentioned in (b), Harry can be the only friend who printed 20 sheets. Also, from (f), Harry could not have visited on Thursday (since he printed 20 sheets). Hence, Harry must have went to the shop on Friday.
From (a), Jacob could have visited the shop on either Wednesday or Thursday. By comparing this with five friends in (b), Jacob must be the one who made an assignment on Biology.
In addition to that, Patrick did not visit the shop on Monday as evident from (f). Hence, Patrick must have visited the shop on Tuesday and Richard on Monday.
As per the information given in (d), it can be concluded that Richard must have taken a copy of 10 sheets more than that of Harry (who went to the shop on Friday). Hence, Richard must have printed 30 sheets. Moreover, from (c), Jacob must have taken a copy of 40 sheets. Furthermore, Jacob must have visited the shop on Thursday as evident from (f). Neil must have printed 50 sheets and went to the shop on Wednesday.
Since Jacob went on Thursday, the friend who visited the shop on Tuesday (Patrick) must have made an assignment on Economics (as evident from (a)). Richard did not made the assignment on Ecology (as evident from (d)). Hence, Neil must have made the assignment on Ecology and Richard must have covered the Chemistry.

The table below presents this information:

Average daily number of sheets printed in the first three days (Monday, Tuesday, Wednesday) of the week = (30 + 10 + 50)/3 = 30
Average daily number of sheets printed in the last two days (Thursday, Friday) of the week = (40 + 20)/2 = 30
Therefore, the difference is 0.

Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 16

Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 5 - Question 16

Titli produced the answer to 8 across, which had the same number of letters as the previous answer to be inserted, and one more than the subsequent answer which was produced by one of the men. So, Titli must have produced a 7-letter word, i.e. either 'Silence' or 'Rosebud'. The word next to Titli's word must be a 6-letter word, which is 'Burden'. It cannot be 'Barely' because it has been given that 'Barely' was the first word to be entered. Also, the word preceding Titli's word must be a 7-letter word.
Thus, both the 7-letter words and 'Burden' must be at consecutive places. They can be at either the second, third and fourth positions or the third, fourth and fifth positions. But, in the second case, 'Baadshah' would be at the second position, which is not possible as given in the question. So, both the 7-letter words and 'Burden' must be at the second, third and fourth positions, respectively, and 'Baadshah' would be at the fifth position. Also, 'Silence' is not at the third position. So, it must be at the second position and 'Rosebud' must be at the third position.

15 across and 15 down must start from the same letter and their length must be unequal. Also, 'Silence' is the answer to an across clue which can be either 15 across or 21 across. However, if 'Silence' is the answer to 15 across, the answer to 15 down must also start with 'S'. But there is no other word starting with 'S'; so 'Silence' must be the answer to the 21 across clue. The fifth one to be worked out was the answer to an across clue. So, 'Baadshah' should be the answer to an across clue.
Elsie's word was longer than Bineet's. So, Elsie's word must be either 'Baadshah' or 'Silence' and Bineet's word should be either 'Barely' or 'Silence'. In both the cases, 'Burden' would be Easwar's word and it would be the answer to the 15 down clue because 'Burden' has been produced by one of the men but it is not Bineet according to instruction 2 and Easwar did not solve 4 down. Sheela was neither the first nor the last to come up with an answer. So, her answer must be 'Silence'. Bineet's word must be 'Barely' and Elsie's word must be 'Baadshah'.
