Question

The ratio of the ages of two persons is 4:7 and age of one of them is greater than that of the other by 30 years. The sum of their ages

Answer 1

Answer:

110

Step-by-step explanation:

given ratio = 4 : 7 = 4x : 7x

7x = 4x + 30

7x - 4x = 30

3x = 30

x = 30 ÷ 3 = 10

So 4x = 4 × 10 = 40

7x = 7 × 10 = 70

Sum of their ages = 70 + 40 = 110
