Answers :

1) Answer: B

Let the work finished in x days

A’s one day work = 1/14

B’s one day work = 1/28

C’s one day work = 1/32

x/14 + (x-3)/28 + (x-2)/32 = 1

=> (16x + 8x – 24 + 7x – 14)/224 = 1

=> 31x = 224 + 38

=> x = 262/31

=> x = 8 (14/31) days


2) Answer: A

LCM of 16 and 20 = 80 units

(A + B)’s one day work = 5 units

(B + C)’s one day work = 4 units

A’s 6 days work + B’s 9 days work + C’s 22 days work = 80

(A + B)’s 6 days work + (B + C)’s 3 days work + C’s 19 days work = 80

(5*6) + (4*3) + C’s 19 days work = 80

C’s 19 days work = 80 – 30 – 12 = 38

C’s one day work = 38/19 = 2 units

C alone can complete the work in, (80/2) = 40 days


3) Answer: D

A + B = 300/100 * 10 = 30 days

C + D = 100/85 * 17 = 20 days

A + B + C = 2/1 * 7.5 = 15 days

C = 1/15 – 1/30 = 1/30

D = 1/20 – 1/30 = 1/60

A + D = 300/200 * 16 = 24 days

A = 1/24 – 1/60 = (5 – 2)/120 = 1/40

B = 1/30 – 1/40 = 1/120

B complete 40% of the work = 40/100 * 120 = 48 days


4) Answer: B

A = 4/3 * 9 = 12 days

A + B = 100/60 * 4.8 = 8 days

B = 1/8 – 1/12 = 3 – 1/24 = 1/24

Ratio of the amount received by A and B = 1/12:1/24 = 2:1

Required difference = 1/2 * 5000 = 2500


5) Answer: B

A = 9/4 * 20 = 45

B = 2/1 * 15 = 30

C = 5/4 * 36 = 45

(x + 5/45) + (x + 5/30) + (x/45) = 1

2x + 10 + 3x + 15 + 2x = 90

7x = 65

x = 65/7 = 9(2/7)

Total time = 5 + 9(2/7) = 14(2/7) days


6) Answer: E

A = 100/75 * 15 = 20 days

B = 100/60 * 18 = 30 days

First 2 days complete the work = 1/20 + 1/30 = 5/60 = 1/12

After 6 times of 2 days = 6/12 = 1/2

After 6 * 2 = 12 days half of the work is completed.


7) Answer: E

A + B complete the whole work = 100/60 * 216/25 = 14(2/5) days

B + C complete whole work = 100/80 * 36/5 = 9 days

B + C complete the work in 4 days = 4/9

Remaining work = 5/9

A alone complete the whole work = (40/3)/(5/9) = 24 days

B = 5/72 – 1/24 = 2/72 = 1/36

C = 1/9 – 1/36 = 3/36 = 1/12


8) Answer: B

18 men can complete the work in (x – 6) days

One man can complete the work in 18 * (x – 6) days

10 men can complete the same work in (y + 2) days

One man can complete the same work in 10 * (y + 2) days

Since, the work is same

18 * (x – 6) = 10 * (y + 2)

9 * (x – 6) = 5 * (y + 2)

9x – 54 = 5y + 10

9x – 5y = 64 (equation 1)

Also, 20 women can complete the work in (x – 2) days

1 women can complete the work in 20 * (x – 2) days

16 women can complete the work in (y + 4) days

One woman can complete the work in 16 * (y + 4) days

Since, the work is same

20 * (x – 2) = 16 * (y + 4)

5 * (x – 2) = 4 * (y + 4)

5x – 10 = 4y + 16

5x – 4y = 26 (equation 2)

Solving equation 1 and equation 2, we get

x = 126/11 and y = 86/11

Therefore,

x – y = (126/11) – (86/11)

x – y = 40/11


9) Answer: D

(x – 5) person can do the work in = x days

(x – 5)*x = (x + 10) (x – 10)

x2 – 5x = x2 – 100

5x = 100

x = 20

Person         days

15                    20

25                    ?

(15 * 20) = 25*y

y = 300/25 = 12 days


10) Answer: B

A + B + C = 1/9

C + D = 100/75 * 6 = 8

d) 1/3y + 1/2y + 1/2y= 1/9

(2 + 3 + 3)/6y = 1/9

8/6y = 1/9

1/y = 1/12

C alone complete the work = 2 * 12 = 24 days

D = 1/8 – 1/24 = 2/24 = 1/12
