If 6 years are subtracted from the present age of Gagan and the remainder is divided by 18, then the present age of his grandson Anup is obtained. If Anup is 2 years younger to Mahesh whose age is 5 years, then what is Gagan's present age?
The sum of the ages of a mother and her daughter is 50. Twelve years ago, the mother was 12 times as old as her daughter. What is the daughter's present age?
K = 4S. K + 10 = 2(S + 10) => 4S + 10 = 2S + 20 => 2S = 10 => S = 5. K = 4(5) = 20 years.

The present age of a father is 3 years more than three times the age of his son. Three years hence, father's age will be 10 years more than twice the age of the son. Find the present age of the father.
F = 3S + 3. After 3 years: F + 3 = 2(S + 3) + 10. Substitute F: (3S + 3) + 3 = 2S + 6 + 10 => 3S + 6 = 2S + 16 => S = 10. F = 3(10) + 3 = 33 years.

The age of a man is three times the sum of the ages of his two sons. Five years hence, his age will be double the sum of the ages of his sons. The father's present age is:
Let sum of sons' ages be S. Father F = 3S. After 5 years, F + 5 = 2(S + 10) (since there are 2 sons, sum increases by 10). 3S + 5 = 2S + 20 => S = 15. Father = 3 * 15 = 45 years.

The ratio of the ages of a father and son is 5 : 2. If the product of their ages is 1000, then what is the age of the father after 10 years?
