Question

4. A number when added to its half gives 72. Find the nunber​

Answer 1

Answer:

Let that number be 'x'.

It is said that the number when added to it's half gives 72.

$\implies \sf x + \dfrac{x}{2} = 72$

LCM of 2 and 1 is 2, So

$\sf \dfrac{(2x+x)}{2} = 72$

2x+x = 72×2

3x = 144

$\sf x = \dfrac{144}{3}$

$\implies \sf x = 48$

The required number is 48 .

Verification

Half of 48 is 24

48 + 24 = 72
