Answer 2

• Let present age of Rahul be 5M and present age of Haroon be 7M.

» 4 years later.

Age of Rahul = 5M + 4

And age of Haroon = 7M + 4

» Four years later the sum of their age will be 56 years.

=> 5M + 4 + 7M + 4 = 56

=> 12M + 8 = 56

=> 12M = 56 - 8

=> 12M = 48

=> M = 4

_____________________________

Present age of Rahul = 5M = 5 × 4 = 20 years.

Present age of Haroon = 7M = 7 × 4 = 28 years.

_________________ [ANSWER]

✡ 5M + 4 + 7M + 4 = 56

Put value of M = 4 in above equation.

=> 5(4) + 4 + 7(4) + 4 = 56

=> 20 + 4 + 28 + 4 = 56

=> 56 = 56
