Answer 2

Answer:

Ali's age is 12 and Bilal's age is 18

Step-by-step explanation:

Given data  

Bilal is 6 years older than Ali

five years from now sum of their age will be 40

here we need to find ages of both of them

let x be the present age of Ali then Bilal age will be x + 6

⇒ present ages of Bilal and Ali are x + 6 and x

⇒ after 5 years ages will be  

               Ali age = x + 5

             Bilal age = x + 6 + 5 = x +11

given that after 5 years from now sum of their ages = 40    

⇒ x + 5 + x + 11 = 40

⇒ 2x + 16 = 40

⇒ 2x  = 40 - 16

⇒ 2x = 24      

⇒ x = 12

⇒ Ali's age x = 12

   Bilal's age = x + 6 = 12 + 6 = 18

             ⇒Ali's age is 12 and Bilal's age is 18
