$\frac{20}{120} \times100 = 16.66\%$

Answer 2

Given :

Y is 20% more than x

To Find :

Find x is less than y by what percent

Solution:

We are given that Y is 20% more than  x

So, y = x+0.2x =1.2 x

Difference = 1.2x-x=0.2x

So, x is less than y by percent =$\frac{0.2x}{1.2x} \times 100=16.67\%$

Hence x is 16.67% less than y
