Question 1
The ratio of Samantha's age to Nandini's age is 4:11. After 28 years, the ratio will become 5:14. Find Samantha's present age.
Let Samantha = 4k, Nandini = 11k
After 28 years: (4k+28)/(11k+28) = 5/14
Solving gives k = 10, so Samantha = 40
After 28 years: (4k+28)/(11k+28) = 5/14
Solving gives k = 10, so Samantha = 40
