Answers
Step-by-step explanation:
If 15 men working for 9 hours a day can reap a field in 16 days, how many days will it take 18 men to reap the field if they work for 8 hours a day?
Friends…!
If 15 men working for 9 hours a day can reap a field in 16 days
The total work for reaping the field is
= 15 men × 9 hours × 16 days
= 2160 man-hour-days
How many days will it take 18 men to reap the field if they work for 8 hours a day?
Work done by 18 men working 8 hours a day
= 18 men × 8 hours
= 144 man-hours
Number of days the work will be completed
= Total work in terms of men-hour-days / men hours available
= 2160 men-hour-days / 144 men - hours
= 15 days
Answer : it will take 15 days by 18 men to reap the field if they work for 8 hours a day

Step-by-step explanation:
m1*d1*h1 = m2*d2*h2
m1=25, d1= 20, h1=8; d2=d2, m2= 16, h2=10
25×8×20 = 16×10× d2
d2 = 25×8×20 / 16×10 = 25 days
