Question

the given number is increased by 20% and the resulting number is again increased by 25% .what is the net percentage increase in the number​

Answer 1

Answer:

44%.

Step-by-step explanation:

Suppose original number is 100.

It is increased by 20 %, so result will be 120.

The resulting number is again increased by 20%, that is increased by 120 *20/100, that is increased by 24. The final result will be 120+24 that is 144.

The final result is increased by 44 compared to original number 100.

So increase by 44%.

Answer 2

Given :

• the given number is increased by 20% and the resulting number is again increased by 25%

To find :

• what is the net percentage increase in the number

Solution :

let the number be x

first number = 120/100 x

second number = 125/100 x 120/100

= 125 x 100/100 x 120

= 1.416

so overall change in the number

1.416x - x/x x 100

= 4.16 x 100

= 41.6 %
