1. 3 men or 5 women or 8 boys can finish a work in 38 days. How many days will be required to complete the same work by 6 men , 10 women and 6 boys together ?
- A. 5
- B. 5
- C. 5
- D. 5
Answer: Option D
Explanation:
Work done by 3 men = 5 women = 8 boys
1 man = 8/3 boys
6 men = 16 boys
1 woman = 8/5 boys
10 women = 16 boys
Now, 6 men + 10 women + 6 boys = 16 + 16 + 6 = 38 boys
8 boys need 38 days
1 boy needs (38x8) days
So, 38 boys need (38x8)/38 = 8days
1 man = 8/3 boys
6 men = 16 boys
1 woman = 8/5 boys
10 women = 16 boys
Now, 6 men + 10 women + 6 boys = 16 + 16 + 6 = 38 boys
8 boys need 38 days
1 boy needs (38x8) days
So, 38 boys need (38x8)/38 = 8days
