Step-by-step explanation:

Answer 2

72 trees cut by 32 men in 12 hours

Given :

40 men can cut 60 trees in 8 hours

To find :

No of trees cut by 32 men in 12 hours

Solution :

40 men can cut 60 trees in 8 hours

No of trees cut by 1 man in 8 hours =$\frac{60}{40}$

If 8 men leaves the job then the total men available for work is 32

No of trees cut by 32 men in 8 hours =$\frac{60}{40} \times 32$

No of trees cut by 32 men in 1 hour =$\frac{60 \times 32}{40 \times 8}$

No of trees cut by 32 men in 12 hours =$\frac{60 \times 32}{40 \times 8} \times 12$

No of trees cut by 32 men in 12 hours = 72

Therefore, in 12 hours 32 men will cut 72 trees.
