This chapter is comparing quantities

Answer 1

Answer:

The increase % in the volume will be (100/3)% or 33.33%.

Step-by-step explanation:

We have given;

Initial volume = 90cm^3;

Increased volume = 120cm^3;

Increase in volume = 120cm^3 - 90cm^3

= 30cm^3;

Let the increase in percentage be x;

Hence, x% of 90 = 30cm^3;

x/100 * 90 = 30;

x = 30 * 100 / 90;

= 100/3 or 33.33;

That's all.
