Question

A clerk receives annual salary of 72720 in the year 2016, this is 20% more than his salary in 2015 What was his salary in 2015?​

Answer 1

Answer:

If the annual salary of the clerk is Rs 72720 in 2016, and if it is 20% more than his salary in 2015, then his salary in 2015 was Rs 60600

Step-by-step explanation:

Given salary of the clerk in 2016 = 72720

Let us take X as the salary of clerk in 2015

Given

72720 is 20% more than his salary in 2015

That is,

$72720 = X + \frac{20X}{100} \\\\72720 = X +\frac{X}{5} \\\\72720 = \frac{5X+X}{5} \\\\72720= \frac{6X}{5} \\\\X= \frac{72720*5}{6} \\\\X=60600$

So his salary in 2015 was Rs 60600
