Question

0.6 of a number is 20 less than the original number find the number

Answer 1

Let the number = x
0.6 of x =x-20
6/10x=x-20
x-6/10 x = 20
10/10x-6/10=20
4/10x=20
X=10/4 * 20
x=50

Answer 2

0.6 of a number is 20 less than the original number

To Find :

Find the number

Solution:

Let the number be x

0.6 of a number =0.6x

We are given that 0.6 of a number is 20 less than the original number

So, x-0.6x=20

$\Rightarrow 0.4x=20$

$\Rightarrow x=\frac{20}{0.4}$

$\Rightarrow x= 50$

Hence The number is 50
