Question

Malini will be 6 times her present age after 30 years. Find her Present age.

Answer 1

6x=30+x

let her present age be x.

6x-x=30

5x=30

x=30/5

x=6

Answer 2

Present age of Malini is 6 years.

Given,

Age of Malini in 30 years = 6 times her present age

To Find,

The present age of Malini

Solution,

This problem can be solved using a very simple solution

Let the present age of Malini be x

Then, from the given data, we can deduce the following equation:

$x+30=6x$

This is a basic linear equation in one variable

We can rearrange the equation above to obtain the value of x

$6x-x=30$

$5x=30$

$x=6$

Therefore, the present age of Malini is 6 years
