__SOLUTIONS:__

__DATA INTERPRETATION__1.Average total cost of toothpaste manufactured by Colgate = Rs. (20a + 25b)

Average total cost of toothpaste manufactured by Pepsodent = Rs. (15a + 20b)

Average total cost of toothpaste manufactured by Dabur = Rs. (25a + 30b)

Average total cost of toothpaste manufactured by Sensodyne = Rs. (40a + 50b)

According to question,

(20a + 25b) = (15a + 20b) + 45

(20a – 15a) + (25b – 20b) = 45

5a + 5b = 45

5(a + b) = 45

(a + b) = 45/5 = 9

Therefore, (a + b)² = 92 = 81

Hence, option c.

2.Average total cost of toothpaste manufactured by Colgate = Rs. (20a + 25b)

Average total cost of toothpaste manufactured by Pepsodent = Rs. (15a + 20b)

Average total cost of toothpaste manufactured by Dabur = Rs. (25a + 30b)

Average total cost of toothpaste manufactured by Sensodyne = Rs. (40a + 50b)

According to question,

(20a + 25b) = (15a + 20b) + 45

(20a – 15a) + (25b – 20b) = 45

5a + 5b = 45

5(a + b) = 45

(a + b) = 45/5 = 9 … (i)

Also, (25a + 30b) = (40a + 50b) – 160

(40a – 25a) + (50b – 30b) = 160

15a + 20b = 160

5(3a + 4b) = 160

(3a + 4b) = 160/5 = 32 … (ii)

Solving equation (i), and (ii), we get, a = 4, and b = 5

Therefore, Average total cost of toothpaste manufactured by Pepsodent = Rs. (15 × 4 + 20 × 5) = Rs. 160

Average total cost of toothpaste manufactured by Dabur = Rs. (25 × 4 + 30 × 5) = Rs. 250

Therefore, required percentage = (160/250) × 100 = 64%

Hence, option d.

3.Average total cost of toothpaste manufactured by Colgate = Rs. (20a + 25b)

Average total cost of toothpaste manufactured by Pepsodent = Rs. (15a + 20b)

Average total cost of toothpaste manufactured by Dabur = Rs. (25a + 30b)

Average total cost of toothpaste manufactured by Sensodyne = Rs. (40a + 50b)

According to question,

(20a + 25b) = (15a + 20b) + 45

(20a – 15a) + (25b – 20b) = 45

5a + 5b = 45

5(a + b) = 45

(a + b) = 45/5 = 9 … (i)

Also, (25a + 30b) = (40a + 50b) – 160

(40a – 25a) + (50b – 30b) = 160

15a + 20b = 160

5(3a + 4b) = 160

(3a + 4b) = 160/5 = 32 … (ii)

Solving equation (i), and (ii), we get,

a = 4 and b = 5

So, Average total cost of toothpaste manufactured by Pepsodent = Rs. (15 × 4 + 20 × 5) = Rs. 160

Therefore, average total cost of toothpaste manufactured by Patanjali = Rs. 160 × 1.25 = Rs. 200

According to question,

(4 × AVC) + (5 × 16) = 200

AVC = (200 – 80)/4 = Rs. 30

Hence, option b.

4.Average total cost of toothpaste manufactured by Colgate = Rs. (20a + 25b)

Average total cost of toothpaste manufactured by Pepsodent = Rs. (15a + 20b)

Average total cost of toothpaste manufactured by Dabur = Rs. (25a + 30b)

Average total cost of toothpaste manufactured by Sensodyne = Rs. (40a + 50b)

According to question,

(20a + 25b) = (15a + 20b) + 45

(20a – 15a) + (25b – 20b) = 45

5a + 5b = 45

5(a + b) = 45

(a + b) = 45/5 = 9 … (i)

Also, (25a + 30b) = (40a + 50b) – 160

(40a – 25a) + (50b – 30b) = 160

15a + 20b = 160

5(3a + 4b) = 160

(3a + 4b) = 160/5 = 32 … (ii)

Solving equation (i), and (ii), we get,

a = 4, and b = 5

Therefore, Average total cost of toothpaste manufactured by Sensodyne = Rs. (40 × 4 + 50 × 5) = Rs. 410

Average total cost of toothpaste manufactured by Colgate = Rs. (20 × 4 + 25 × 5) = Rs. 205

Therefore, required ratio = 410: 205 = 2: 1

Hence, option e.

5.Average total cost of toothpaste manufactured by Colgate = Rs. (20a + 25b)

Average total cost of toothpaste manufactured by Pepsodent = Rs. (15a + 20b)

Average total cost of toothpaste manufactured by Dabur = Rs. (25a + 30b)

Average total cost of toothpaste manufactured by Sensodyne = Rs. (40a + 50b)

According to question,

(20a + 25b) = (15a + 20b) + 45

(20a – 15a) + (25b – 20b) = 45

5a + 5b = 45

5(a + b) = 45

(a + b) = 45/5 = 9 … (i)

Also, (25a + 30b) = (40a + 50b) – 160

(40a – 25a) + (50b – 30b) = 160

15a + 20b = 160

5(3a + 4b) = 160

(3a + 4b) = 160/5 = 32 … (ii)

Solving equation (i), and (ii), we get,

a = 4, and b = 5

Average total cost of toothpaste manufactured by Dabur = Rs. (25 × 4 + 30 × 5) = Rs. 250

Therefore, Economic profit (EP) of Dabur = Total revenue (TR) – average total cost (ATC) = 400 – 250 = Rs. 150

Therefore, EP (%) = [(TR – ATC)/ATC] × 100 = (150/250) × 100 = 60%

Hence, option a.

__ARITHMETIC SUM__

__DATA INTERPRETATION__11.Total amount deposited in bank by A = 894 × 10 + 647 × 50 + 512 × 100 + 215 × 500

= 8940 + 32350 + 51200 + 107500

= Rs. 199990

Total amount deposited in bank by D = 1149 × 10 + 716 × 50 + 438 × 100 + 299 × 500

= 11490 + 35800 + 43800 + 149500

= Rs. 240590

Required difference = 240590 – 199990 = Rs. 40600

Hence, option b.

12.Total number of Rs. 500 notes deposited in the bank = 215 + 308 + 294 + 299 + 356 = 1472

Required amount = 1472 × 500 = Rs. 736000

Hence, option d.

13.Total number of Rs. 100 notes deposited in the bank = 512 + 505 + 597 + 438 + 419 = 2471

Total number of Rs. 50 notes deposited in the bank = 647 + 622 + 782 + 716 + 621 = 3388

Required % = (2471/3388) × 100 ~ 72.9%

Hence, option c.

14.Required amount = 785 × 10 + 622 × 50 + 505 × 100 + 308 × 500

= 7850 + 31100 + 50500 + 154000

= Rs. 243450

Hence, option d.

15.Total amount deposited in bank C through Rs. 10 notes = 1056 × 10 = Rs. 10560

Total amount deposited in bank C through Rs. 500 notes = 294 × 500 = Rs. 147000

Required ratio = 10560:147000 = 88:1225

Hence, option e.

__ARITHMETIC SUM__16) Answer: D

Revenue in 1 hour that will be generated = 100(50 + x) × (100 – 20 –1.5x)/100

The cost will be = 40(50 + x) × (100 + 2x)/100

Then Profit in the whole process = 2000 – 2.3x2 – 75x

So, if profit > 0, then x < 17.38

=>Hence maximum increase in production that can be taken without loss = 17.

17) Answer: C

Raja’s profit = (1 apple and 1 banana) on (2 apple and 5 banana) = 35%

=>apple + banana = 35/100(2 apple + 5 banana)

=> solving we get = 6 apple = 15 banana

=> apple/banana = 5/2

So, my effective profit = 1 apple on (3 apple and 5 banana)

= 1 apple / 3 apple + 5(2/5) apple

= 1 apple / 5 apple × 100 = 20%

Hence, my effective profit for the whole transaction is = 20%.

18) Answer: B

Getting one girl and two boys can be possible in three disjoint cases:

So P(I) = 3/4 × 2/4 × 3/4 = 9/32

P(II) = 1/4 × 2/4 × 3/4 = 3/32

P(III) = 1/4 × 2/4 × 1/4 = 1/32

So, the required probability = P(I) + P(II) + P(III)

=>9/32 + 3/32 + 1/32 = 13/32.

19) Answer: C

5 out of 7 days can be selected in 7c5 ways. In those 5 days, Kajal has to go to Basketball.

Probability = (2/3)5

On the other 2 days she has to go for football practice.

Probability = (1/3)2

Therefore required probability

= 7c5 × (2/3)5 × (1/3)2

= 224/729.

20) Answer: C

12 = (3 × 4).The number formed by all these digits will always be divisible by 3, because (6 + 7 + 8 + 0) = 21.

For divisibility by 4, last two digits should be 60 or 80 or 08 or 68 or 76.

If the last two digits are fixed we must make sure that the first digit is non-zero.

Case I: Last two digits are 60 or 80 or 08.

The first two digits can be arranged in 2 × 1 = 2 ways.

Case II: Last two digits are 68 or 76.

The first two digits can be arranged in 1 way, because the first digit cannot be 0.

So, sum = [(78 + 87) × 100 + 2 × 60] + [(67 + 76) × 100 + 2 × 80] + [(67 + 76) × 100 + 2 × 08] + 7068 + 8076 = 60540.

__DATA SUFFICIENCY__21.EITHER 1 OR 2 IS SUFFICIENT

22.ONLY 2 IS SUFFICIENT

23.BOTH 1 AND 2 TOGETHER NECESSARY

24.Statement I:

Let they meet after x hours

Then, ￼ 75x - 60x = 180

=> X = 12 hours

Therefore, distance between Darbhanga and Patna = ￼60 x 12 + 75 x 12 = 1620 km

So, statement I alone is sufficient to answer the question.

Statement II:

Time after which train meets = 12 hours

Therefore, required distance = ￼￼60 x 12 + 75 x 12 = 1620 km

So, statement II alone is sufficient to answer the question.

Thus, the data either in Statement I or in Statement II alone are sufficient to answer the question.

So option (C) is the correct answer.

25.Let, marked price of the article = Rs. x

And, cost price of the item = Rs. y

According to the question: 1.7y = 0.85x

And, ￼1.5y = 0.85x - p

Statement I:

P = 200

We get, ￼1.7y = 1.5y + 200

￼=> y= 1000

So, statement I alone is sufficient to answer the question.

Statement II:

￼x=2000

So, discount price = ￼2000 × 0.15 = 300

So, cost price = ￼(2000 - 300)/1.7 = 1000

So, statement II alone is sufficient to answer the question.

Thus, the data either in Statement I or in Statement II alone are sufficient to answer the question.

So option (C) is the correct answer.
