At present, Anil's age is ` 1.5` times the age of Purvi. Eight years hence, the ratio of the ages of Anil and Purvi will be ` 25 : 18`. What is Purvi' s present age ?

Options

A. 50 year
B. 28 year
C. 42 year
D. 36 year

Explanation

Let Purvi's present age be x years .
Anil's present age ` 1.5 x` years.
Age after eight years = `(1.5x+8)/(x+8) = (25)/(18) ` or, ` 27x+144=25x+200 or, 2x = 56`
`:. X = 28`
