Sum of the present ages of A, B, C and D is 55 years. After 5 years ratio of their ages is 5:4:3:3. What is C’s present age?
At present sum of age = 55 years After 5 years sum of age will be, => 5x + 4x + 3x + 3x = 55 + 5 × 4 => 15x = 55 + 20 => x = 75/15 => x = 5 C’s present age = 3x – 5 = 10 years
