ANSWER:

1) Answer: B

Explanation:

The total number of notebooks sold on Monday

= > 420 + 260 = 680

The total number of notebooks sold on Friday

= > 360 + 400 = 760

Required difference = 760 – 680 = 80

2) Answer: D

Explanation:

Total number of notebooks sold on Tuesday

= > 480 + 320 = 800

Total number of notebooks sold on Wednesday

= > 540 + 380 = 920

Total number of notebooks sold on Saturday

= > 920 * (140/100) = 1288

Required % = (800/1288) * 100 = 62.11% = 62 %

3) Answer: A

Explanation:

The average number of plain notebooks sold on all the

given days together

= > (420 + 480 + 540 + 600 + 360)/5 = 480

The average number of ruled notebooks sold on all the

given days together

= > (260 + 320 + 380 + 440 + 400)/5 = 360

Required difference = 480 – 360 = 120

4) Answer: C

Explanation

The total number of plain notebooks sold on Monday,

Wednesday and Friday together

= > 420 + 540 + 360 = 1320

The total number of ruled notebooks sold on Tuesday,

Wednesday and Thursday together

= > 320 + 380 + 440 = 1140

Required ratio = 1320 : 1140 = 22 : 19

5) Answer: E

Explanation:

The total number of notebooks sold on Thursday

= > 600 + 440 = 1040

The total number of non defective notebooks sold on

Thursday

= > 1040 * (5/8) = 650

6) Answer: A

Profit on A = 12%

Overall profit = 15%

Profit on B = (15 * 2) - 12 = 18%

=> 90/18 * 100 = 500

CP of A = 500

27) Answer: B

M1 * W1 = M2 * W2

40 * 48 = 64 * x + 96 * 16(2/3)

1920 = 64x + 1600

x = 5

7) Answer: B

M1 * W1 = M2 * W2

40 * 48 = 64 * x + 96 * 16(2/3)

1920 = 64x + 1600

x = 5

8) Answer: A

In initial mixture,

Water = 24%

Milk = 76%

In 50 liter,

Water = 50/100 * 24 = 12

Milk = 50/100 * 76 = 38

Remaining milk = 76/76 * 100 = 100

Initial milk = 100 + 38 = 138 lit

9) Answer: D

The ratio of speed of boat and current = 10 :1

Downstream speed = 10 + 1 = 11

Upstream speed = 10 -1 = 9

Downstream speed : Upstream speed = 11 : 9

Time ratio = 9: 11

The ratio of time taken to travel the distance “D " in

downstream and D - 45

= 3 : 2

Let

Time to travel D = 9 (from above ratio)

Time to travel D – 45 = 9/3 * 2 = 6h

Then the Distance D = 45/(9 - 6) * 9 = 135 km

10) Answer: D

The profit ratio =( x * 2) : x + 4000

2x/(3x + 4000) = 3/7

14x = 9x + 12000

5x = 12000

x = 2400
