Rajeev's age is four more than the age of Shilpa. The age of Shilpa can be obtained by subtracting four times her age 4 years ago from the four times her age after 4 years. What was Rajeev's age before 4 years ?
Solution
Correct Answer: Option C
Let Shilpa's present age is p years
According to question,
p = 4(x+4) – 4(x–4)
p = 4x+16 – 4x+16
p = 32
Shilpa's present age = 32 years
Rajeev is four years older than Shilpa
=> Shilpa's present age = Rajeev's age 4 years before.
=> Rajeev's age 4 years before = 32 years.
