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 |
