Question 1
9 years ago, the ratio of Kishore's age to Nidhi's age was 3:8. 18 years from now, the ratio will be 4:11. Find Kishore's present age.
Let Kishore's present age = x, Nidhi's present age = y
9 years ago: (x-9)/(y-9) = 3/8
18 years from now: (x+18)/(y+18) = 4/11
Solving these equations gives x = 27, y = 72
9 years ago: (x-9)/(y-9) = 3/8
18 years from now: (x+18)/(y+18) = 4/11
Solving these equations gives x = 27, y = 72
