The age of Mira’s mother is 4 times the age of Mira. 5 years later, her mother’s age will be 3 times that of Mira’s age. Find the present age of her mother.
A
35 years
B
25 years
C
40 years
D
45 years
Correct Option:
C
Explanation
Let Mira's present age be x. Her mother's age is 4x. After five years: 4x + 5 = 3(x + 5). So 4x + 5 = 3x + 15, giving x = 10. The mother's present age is therefore 4 × 10 = 40 years.
