Question

If a number of which the half is greater than1/5th of the number by 15 then the number is

Answer 1

Let the number be '2x', so we have

1/2 (2x) - 1/5 (2x) = 15

[1/2 - 1/5] (2x) = 15

[5/10 - 2/10] (2x) = 15

3/10 (2x) = 15

3/5 x = 15

x = 15 (5/3)

x = 25

So our number is 2x, so we get

2(25) = 50
