Question

if tree fourth of a number is 60.then half the number is

Answer 1

Let the number be 'x'. x = ?


We have 

(3/4) * x = 60 + (1/3)*x

If we multiply both sides of the equation by 12 we get

(3*12/4) * x = 60 * 12 + (12/3)*x

9x = 720 + 4x

9x - 4x = 720

5x = 720


x = 144


Indeed for x = 144 we have

3/4 of 144 is 108

1/3 of 144 is 48 

And the difference between them is 108 - 48 = 60 as required.


The number is 144.

Answer 2

Three fourth of a number is 60
Then3/4 of number=60
So no.=60×4/3=80
Half of 80 is 40.
So 40 is the answer.
