Question

Sonia's father is 24 years younger than Sonia's grandfather and 25 years older than sonia. sum of their ages is 104 years. What are the ages of each one of them?​

Answer 1

Sonia's age = x

Sonia's father's age = x + 25

Sonia's grandfather = (x + 25) + 24 = x + 25 + 24 = x + 49

Sum of their ages = 104

x + (x + 25) + (x + 49) = 104

x + x + 25 + x + 49 = 104

3x + 74 = 104

3x = 104 - 74

3x = 30

x = 30/3

x = 10

Sonia's age = x = 10 years

Sonia's father's age = x + 25 = 10 + 25 = 35 years

Sonia's grandfather's age = x + 49 = 10 + 49 = 59 years
