Question

Twice a number added to half of itself equals 24. Find the number.

Answer 1

let the number be x

twice of x = 2x
half of x =x/2

2x +x/2 =24
(4x +x)/2 =24

4x +x =48
5x =48
x =48/5

Answer 2

let the no. be x
2x/1 + x/2 = 24
by talking the L.C.M of 1 and 2 we get
4x + x = 24×2
5x = 48
x = 48/5
x = 9.6
