The key to solving such questions is to use per day work and then create an equation
Let a man do M work a day. 15 Men will do 15M work
15M x 28 = Total field work
If men gets reduced to 10, 10M would be daily work
Let 10 men work for y days
10M x y = 15M x 28
y = 42
Fifteen men can harvest a field in 28 days. How long will it take to harvest this field if the number of men is reduced to 10?
