The ratio of the present ages of Smithers and Homer is 3 : 5. After 7 years, Homer's age will be 42 years. What will be Smithers' age after 8 years?

23 years 22 years 29 years 31 years

29 years

ATQ, Let Smithers' age is 3x and Homer's age is 5x Given, 5x + 7 = 42            x = 7 So, Smithers' age after 8 years = 3 × 7 + 8 = 29 years
