Answer» Correct Answer - Option 1 : 20 Given: 12 men or 24 boys can do a work in 30 days. Calculations: Let the amount of work done by 1 man in 1 day be M. and the amount of work done by 1 boy in 1 day be B. according to the question, 12 × M × 30 = 24 × B × 30 so M ∶ B = 2 ∶ 1 so total amount of work = 24 × 1 × 30 = 24 × 30 now work done by 15 men and 6 boys in 1 day = 15 × 2 + 6 × 1 = 36 so the number of days taken by 15 men and 6 boys to complete the work = (24 × 30)/36 = 20 days ∴ the correct answer is 20 days.

Answer» Correct Answer - Option 1 : 20

Given:

12 men or 24 boys can do a work in 30 days.

Calculations:

Let the amount of work done by 1 man in 1 day be M.

and the amount of work done by 1 boy in 1 day be B.

according to the question,

12 × M × 30 = 24 × B × 30

so M ∶ B = 2 ∶ 1

so total amount of work = 24 × 1 × 30 = 24 × 30

now work done by 15 men and 6 boys in 1 day = 15 × 2 + 6 × 1 = 36

so the number of days taken by 15 men and 6 boys to complete the work = (24 × 30)/36 = 20 days

∴ the correct answer is 20 days.
