Sweety is 54 years old and her mother is 80. How many years ago was Sweety's mother three times her age?
Solution
Correct Answer: Option B
Given P = 54 and M = 80
According to the question,
Let ‘A’ years ago, M = 3P
=> M - A/P - A = 3
=> 80 - A = 3(54 - A)
=> 80 - A = 162 - 3A
=> 2A = 82
=> A = 41
Therefore, A = 41 years ago Sweety’s mother was 3 times of Sweety’s age.
Hence, at the age S = 13 and M = 39.
