Question

Mobile users in India have gone up by 20% in a year. There are 540 million mobile users today. How many mobile users were there in India last year?

Answer 1

Answer: There are 450 million mobile users in India last year.

Explanation:

Since we have given that

Number of mobile users today = 540 million

Every year mobile users in India have gone up by 20% in a year.

Let the number of mobile users in India last year be x

So, According to question, we have,

`x* (100+20)/(100)=540\\\\x*(120)/(100)=540\\\\x* 1.2=540\\\\x=(540)/(1.2)\\\\x=450`

Hence, there are 450 million mobile users in India last year.
