Sanchi's age after 15 years will be 4 times her age 6 years back. What is the present age of Sanchi ?
Answer & explanation
Correct answer: option 3
Let the present age of Sanchi = a years
Sanchi's age after 15 years = a + 15
Sanchi's age 6 years ago = a - 6
ATQ,
(a + 15) = 4 × (a - 6)
3a = 24 + 15
a = 13
So Present age of Sanchi = 13 years.
