## Answers ( )

## Answer :

❍ 10

## Explanation :

According to the question :☃️ Let the number be

‘n‘❄ Twice number = 2n

❄ Half it’s value = n / 2

Equation :=> 2n = 15 + n / 2 [ LCM = 2 ]

=> 2n = ( 15 × 2 ) + n / 2

=> 2n = 30 + n / 2

=> 2n + n = 30 + n

=> 4n = 30 + n

=> 4n – n = 30

=> 3n = 30

=> n = 30 / 3

=> n = 10## ❥ So, It’s Done ❥ !!

According to question}Hence
