Question

A number when added to its half given 63. find the number​

Answer 1

$x + \frac{1}{2} x = 63 \\ 3x = 126 \\ x = 42$

42 is the no.

Answer 2

Let the number be x. Then its half will be (x/2).

So,

x + (x/2) = 63

(2x/2) + (x/2) = 63

(2x + x)/2 = 63

3x/2 = 63

x = 63 × 2/3

x = 42

Hence 42 is the answer.
