Question

In a newspaper, it was reported that yearly robberies in Springfield were up 26% to 315 in 2014 from 2013. How many robberies were there in Springfield in 2013?

Answer 1

The number of robberies in Springfield in 2013 is 250.

Step-by-step explanation:

Here let us assume that the number of robberies in 2013 = m

Given the number of robberies in 2014 = 315

As we can see the robberies has risen by 26% .\

⇒  26%   + 100 % of Robberies in 2013  = 315

⇒ 126% of m   = 315

$\implies \frac{126}{100} \times m = 315\\\implies m = \frac{315 \times 100}{126} = 250$

or, m = 250

Hence, the number of robberies in Springfield in 2013 is 250.
