Question

15 masons can build tha wall in 20 days. How many masons will build the wall in 12 days?

Answer 1

If 50 masons can build wall in 20 days.

Then we can take the Equation as :

1/ 50 = 1/ 20 days ------------------------------------------------------ 1.

then , 1/ ? = 1/ 12   ------------------------------------------------------ 2.

Cross Multiplying both the terms.

Then, 1 / 50 * 1 / 12 = 1 / 20 * 1 / x . [ Assumption as x ]

then,  1 / 50 * 1 / 12 * 20 = 1 / x

So, Simplifying the Equation.

then, We get 1 / 30 = 1 / x

Then again cross Multiplying

Then we get, x = 30.

So we can state that 30 masons can build a wall in 12 days.
