Answer»

Let assume current age of Suresh, Ramesh and Mahesh as x, y and z respectively,

For the sum of the age of Suresh and Ramesh,

[(x - 4) + (y - 4)]/2 = 36

⇒ x + y - 8 = 72

⇒ x + y = 80----(I)

From the data given in the question,

⇒ [x + y + z]/3 = 40

⇒ x + y + z = 120

Substitute the value of EQ(I) in above EQUATION,

⇒ 80 + z = 120

⇒ z = 120 - 80 = 40

∴ Age of Mahesh after 7 years = 40 + 7 = 47 years
