Let's say the current age \(= x\) years
In \(h\) years, John will be \(3k + 1\) times his current age.
\(x + h = (3k + 1) (x)\)
\(x + h = 3kx + x\)
\(x = \frac{h}{3k}\)
Answer \(D\)
In \(h\) years, John will be \(3k + 1\) times his current age.
\(x + h = (3k + 1) (x)\)
\(x + h = 3kx + x\)
\(x = \frac{h}{3k}\)
Answer \(D\)
