Question
At present, Naveen is six years younger than Mohit.
Mohit’s age fifteen years hence will be equal to thrice that of Naveen three years ago. What will be the sum of their present age?Solution
Mohit = x Naveen = (x-6) 15 years hence, Mohit’s age = (x + 15) years 3 years ago, Naveen = x - 6 - 3 = (x - 9) years Now, (x+15) = 3 (x-9) x + 15 = 3x - 27 42 = 2x x = 21 years Hence, Mohit = 21 years Naveen = 21 - 6 = 15 years Sum of the present ages of Mohit and Naveen = 21 + 15 = 36 years
