(a) 44 days 

(b) 33 days 

(c) 55 days 

(d) 66 days

Answer 1

Correct option (a) 44 days

Explanation:

12 men = 24 boys 

15 men 30 boys 

15 men + 6 boys = 30 boys+6 boys =36 boys 

24 boys can do a work in 66 days 

1 boys can do a work in 60 × 24

36 boys can do a work in 66 x 24/36 = 44 days
