Question

The ratio of the ages of A, B and C is 7: 5: 4. If C's age is 32 years, find the sum of the ages of A, B and C (in years).

Answer 1

Answer:

128.

Step-by-step explanation:

ATQ, The ages of A, B, and C are in the ratio 7:5:4.

C's age = 32 years.

Let A's age be 7x.

Let B's age be 5x.

Let C's age be 4x.

Now,

➵ 4x = 32

     x = $\frac{32}{4}$

     x = 8

Thus,

A's age is 7 × 8 = 56 years.

B's age is 5 × 8 = 40 years.

{Calculating Sum of Ages}

➵ 56 + 40 + 32 = 128.

∴ The sum of their ages is 128.
