Answer» Let Viru 's present age = x yrs then Sudhir's present age = (5 + 3x) yrs Anil's present age = (5 + 3x)/2 yrs Ratio of the sum of Sudhir's and Viru's age to three times Anil's age is 5 : 6 e.g., (5 + 3x + x)/3(5 + 3x)/2 = 5/6 => 2(5 + 4x)/3(5 + 3x) = 5/6 => 12(5 + 4x) = 15(5 + 3x)=> 4(5 + 4x) = 5(5 + 3x) => 20 + 16x = 25 + 15x => x = 5 Vinu's age is 5 years.

Answer»

Let Viru 's present age = x yrs then Sudhir's present age = (5 + 3x) yrs Anil's present age = (5 + 3x)/2 yrs

Ratio of the sum of Sudhir's and Viru's age to three times Anil's age is 5 : 6

e.g., (5 + 3x + x)/3(5 + 3x)/2 = 5/6 => 2(5 + 4x)/3(5 + 3x) = 5/6 => 12(5 + 4x) = 15(5 + 3x)=> 4(5 + 4x) = 5(5 + 3x) => 20 + 16x = 25 + 15x => x = 5

Vinu's age is 5 years.
