Here 3 men take 4 days
To finish the same job in 3 days we need more men, in such cases, where on quantity is increasing and one is decreasing, we use inverse proportion .
According to inverse proportion, since the job is same
Men × time taken in ( first situation) = men × time taken ( in second situation)
3 × 4 = men required × 3
∴Men required = 4
4 men required to finish the whitewash in 3 days.
