Question

Six years ago Anita was P times as old as Ben was. If Anita is now 17 years old, how old is Ben now in terms of P ?
A) 11/P + 6
B) P/11 +6
C) 17 - P/6
D) 17/P

Answer 1

Let the present ages of Ben and Anita be x and y respectively.
6 years ago,
y-6=p(x-6)
17-6=p(x-6)
11=p(x-6)
At present,11+6=P(x-6)+6
11=P(x-6)
11/p=x-6
x=11/p+6 (A)
