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 ?
Answer: A
Let Ben’s age now be \(B
\)
Anita's age now be \(A\)
\((A - 6) = P(B - 6)\)
But \(A\) is 17 and therefore, \(11 = P(B - 6)\)
\(\Rightarrow 11/P = B-6\)
\(\Rightarrow (11/P) + 6 = B\)
