Answer 2

Answer:

The number increased by 20% gives 30 = 25

Step-by-step explanation:

Given,

A number increased by 20% gives 30

Solution

Let p be the number

20% of the number = $\frac{20}{100}$× p

When the number 'p' is increased by 20% , we get

p +  $\frac{20}{100}$× p

Since the number increased by 20% gives 30 we get

p +  $\frac{20}{100}$× p = 30

p(1+ $\frac{20}{100}$) = 30

p × $\frac{120}{100}$ = 30

p = $\frac{30 X 100}{120}$

p = 25

∴ The number increased by 20% gives 30 = 25
