Correct Answer: 3 : 7
Explanation:
Let the age of Mona and her mother be 5x and 13x years respectively.
Then, (13x - 5x) = 24
? x = 3
So, their present ages are 15 years and 39 years
Ratio of their ages after 3 years = 18 : 42 = 3 : 7
Correct Answer: 3 years
Explanation:
Let Kamla's age 6 years ago be x years.
So, Kamla's present age = (x + 6) years
? x + 6 = 5x / 4
? 4x + 24 = 5x
? x = 24
So, Kamla's Present age = (x + 6) years = 30 years
? Son's present age = 30/10 = 3 years
Correct Answer: 40 years, 10 years

? x = 35
? the present age of the elder person is 35 years.
Correct Answer: 40 years

? x = 9years
? The son's age = 9 years
Father's age = 45 - 9 = 36 years
Correct Answer: 30 years
