ANSWERS

 

1.

A’s 1 day’s work = 1 ;
15
B’s 1 day’s work = 1 ;
20
(A + B)’s 1 day’s work = 1 + 1 = 7 .
15 20 60
(A + B)’s 4 day’s work = 7 x 4 = 7 .
60 15
Therefore, Remaining work = 1 – 7 = 8 .
15 15

 

 

2. 

Ratio of times taken by A and B = 1 : 3.

The time difference is (3 – 1) 2 days while B take 3 days and A takes 1 day.

If difference of time is 2 days, B takes 3 days.

If difference of time is 60 days, B takes 3 x 60 = 90 days.
2

So, A takes 30 days to do the work.

A’s 1 day’s work = 1
30
B’s 1 day’s work = 1
90
(A + B)’s 1 day’s work = 1 + 1 = 4 = 2
30 90 90 45
 A and B together can do the work in 45 = 22 1 days.
2 2

 

 

3. 

B’s 10 day’s work = 1 x 10 = 2 .
15 3
Remaining work = 1 – 2 = 1 .
3 3
Now, 1 work is done by A in 1 day.
18
1 work is done by A in 18 x 1 = 6 days.
3 3

 

 

4. 

(A + B)’s 20 day’s work = 1 x 20 = 2 .
30 3
Remaining work = 1 – 2 = 1 .
3 3
Now, 1 work is done by A in 20 days.
3

Therefore, the whole work will be done by A in (20 x 3) = 60 days

 

 

5. 

1 woman’s 1 day’s work = 1
70
1 child’s 1 day’s work = 1
140
(5 women + 10 children)’s day’s work = 5 + 10 = 1 + 1 = 1
70 140 14 14 7

 5 women and 10 children will complete the work in 7 days.

 

 

6. 

Work done by X in 4 days = 1 x 4 = 1 .
20 5
Remaining work = 1 – 1 = 4 .
5 5
(X + Y)’s 1 day’s work = 1 + 1 = 8 = 2 .
20 12 60 15
Now, 2 work is done by X and Y in 1 day.
15
So, 4 work will be done by X and Y in 15 x 4 = 6 days.
5 2 5

Hence, total time taken = (6 + 4) days = 10 days

 

 

7. 

Formula: If A can do a piece of work in n days, then A’s 1 day’s work = 1 .
n
(A + B + C)’s 1 day’s work = 1 + 1 + 1 = 7 .
24 6 12 24
Formula: If A’s 1 day’s work = 1 , then A can finish the work in n days.
n
So, all the three together will complete the job in 24  days = 3 3 days.
7 7

 

 

8. 

(A + B)’s 1 day’s work = 1 + 1 = 1 .
15 10 6
Work done by A and B in 2 days = 1 x 2 = 1 .
6 3
Remaining work = 1 – 1 = 2 .
3 3
Now, 1 work is done by A in 1 day.
15
2 work will be done by a in 15 x 2 = 10 days.
3 3

Hence, the total time taken = (10 + 2) = 12 days.

 

9.

I. (10 x 6) men can complete the work in 1 day.

       1 man’s 1 day’s work = 1
60

 

 II. 10 x 24 men + 10 x 24 women can complete the work in 1 day.
7 7
       240 men’s 1 day work + 240 women’s 1 day work = 1.
7 7
       240 x 1 + 240 women’s 1 day’s work = 1.
7 60 7
       240 women’s 1 day’s work = 1 – 4 = 3
7 7 7
       10 women’s 1 day’s work = 3 x 7 x 10 = 1
7 240 8

      So, 10 women can finish the work in 8 days.

 

III. (10 men’s work for 3 days) + (10 women’s work for 4 days) = 1

       (10 x 3) men’s 1 day’s work + (10 x 4) women’s 1 day’s work = 1

       30 men’s 1 day’s work + 40 women’s 1 day’s work = 1

 

      Thus, I and III will give us the answer.

      And, II and III will give us the answer.

       Correct answer is (A).

 

 

10. 

I. 20 work can be completed by (8 x 8) workers in 1 day.
100

   Whole work can be completed by (8 x 8 x 5) workers in 1 day.

        = 8 x 8 x 5 workers in 10 days = 32 workers in 10 days.
10

 

 II. (20 x 16) workers can finish it in 1 day.

   (20 x 16) workers can finish it in 10 days.
10

   32 workers can finish it in 10 days.

III. 1 work can be completed by (8 x 5) workers in 1 day.
8

   Whole work can be completed by (8 x 5 x 8) workers in 1 day.

        = 8 x 5 x 8 workers in 10 days = 32 workers in 10 days.
10

 Any one of the three gives the answer.

 Correct answer is (E).
