Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (A)

**How to Solve**

Required time for 6 girls to complete the work

8 x 12 = 6 x ?

? = 16 days.

4 boys complete the work in 16 days

So, 4 boys one day work is 1 / 16.

6 girls complete the work in 16 days

So, 6 girls one day work is 1 / 16.

So, time required by 4 boys an 6 girls to complete that work is

= (1 / 16) + (1 / 16)

= 8 days.

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (B)

**How to Solve**

Women’s 1 day work = 1 / 10

Mother’s 1 day work = 1 / 12

Son’s 1 day work = 1 / 15

So, time required to do the job if they work together is

(1 / 10) + (1 / 12) + (1 / 15)

= 15 / 60

= 1 / 4

So, it takes to complete the work together is 4 days.

**Answer:**Option (D)

**How to Solve**

Manish’s work in 9 days is ( 1 / 18 X 9 ) = 1 / 2.

So, remaining work is ( 1 – 1 / 2 ) = 1 / 2.

Now, Rahul complete the remaining work in (1 / 16) X 2

= 1 / 8

= 8 days.

Amit + Bikash + Chandan 1 day work = 1 / 40

Amit + Bikash 1 day work = 1 / 60

So, time required for Chandan alone is

(1 / 40) – (1 / 60)

= (3 – 2) / 120

= 1 / 120

So, Chandan alone can complete that work in 120 minutes.

Sir please explain example 1 and example 3

If 10 men or 20 women or 40 children can do a work in 7 months, then what is the required time to do the half of the work by 5 men,5 women and 5 children

Ratio is 4:2:1

And here total work is 210 ×7=1470

But here asking half work so, 735

Therefore,

5m+5w+5c=35

So total time =21 days answer
