Question
The average age of three children is 32 years. If their
ages are in the ratio 3:6:7. Find the age of the youngest child.Solution
Total age of three children = 32 × 3 = 96 years Let their ages be 3x, 6x and 7x respectively. => 3x + 6x + 7x = 96 => 16x = 96 => x = 6 Therefore the age of youngest child = 6 × 3 = 18 years
