p says to q ` ` i am thrice as old as you were when i was as old as you are ' ' . if the sum of their present age is 100 years , then the present age of q ?
let the present age of q be x the age of q years back ( to be defined ) is x / 3 as the age of p will be x by then . years passed = x - x / 3 = 2 x / 3 ( subtracting age of q ) so p acurrent age is x + 2 x / 3 and q current age is x adding them to 100 we get x = 37.5 answer : c
divide(multiply(100, const_3), subtract(multiply(const_3, const_3), const_1))
