Correct Answer - Option 4 : 6
Given:
3 men = 6 boys
6 boys can complete the task in 20 days
Formula used:
Total work = No of people × No of days
Calculation:
1 men = 6/3 boys = 2 boys
⇒ 6 men = 2 × 6 boys = 12 boys
Now, total boys will be (12) + 8 = 20
6 boys can finish a work in 20 days.
∴ 20 boys can complete the work in (20 × 6) ÷ 20 = 6 days
