Question

If 40 per cent of a number is 36.what will be 15 per cent of that number ?

Answer 1

x*40/100=36
x=36*100/40
x=90
90*15/100=13.5

Answer 2

Hey friend!

First let us find the number

Let the number be x

40/100*x=36
2/5*x=36
2x/5=36
2x=36*5
2x=180
X=180/2
X=90

So the number is 90
Now let's find the 15% of 90

15/100*90=
3/20*90=
3/20*90= 13.5

So 15% of that number is 13.5

Hope this helps you!
