Question

In 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B. If 70 houses were built in Town A during 210, how many were built in Town B

Answer 1

The number of houses built in Town B is 56.

Explanation:

We are given that in 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B.

Also, 70 houses were built in Town A during 210.

Let the number of houses built in Town B be 'x'.

So, according to the question;

Number of houses built in Town A = Number of houses built in Town B + 25% of the houses built in Town B

`70 = x + (25\% * x)`

`70 = x(1+0.25)`

`x=(70)/(1.25)`

x = 56

Hence, the number of houses built in Town B is 56.
