Question

Find the number if: 4% of it is 31% of 16.4

Answer 1

The number (x) is 127.1

Explanation:

4% of a number (x) is equal to;

31% of 16.4

i.e 0.04x = 5.084

x =
`(5.084)/(0.04)` = 127.1

The number (x) is 127.1

Answer 2

x = 127.1

Explanation:

Let x be the unknown number.

It is given that 4% of the number is 31% of 16.4

4% of x = 31% of 16.4

`x* (4)/(100)=16.4* (31)/(100)`

`(4x)/(100)=(508.4)/(100)`

Multiply both sides by 100.

`(4x)/(100)* 100=(508.4)/(100)* 100`

`4x=508.4`

Divide both sides by 4.

`x=(508.4)/(4)`

`x=127.1`

Therefore, the unknown number is 127.1.
