Three years ago, Mayank's age was 3 times of her son's age and after 2 years, 4 times of his age will be equal to 9 times his son's age. Find the present age of Mayank .
Answer & explanation
Correct answer: option 4
Let the present age of Mayank = 3x + 3
present age of Mayank's son = x + 3
Now, after 2 years
According to question , 4 ( 3x + 5) = 9( x+ 5 )
12x + 20 = 9x + 45
3x = 25 years
x = \(\frac{25}{3}\) years
present age of Mayank = 3 × \(\frac{25}{3}\) + 3 = 28 years
