"Sunil's Solution"

Chris Smith, Scotland

Saturday, June 1, 2024

"These wordy puzzles are confusing enough to make me want to pull my hair out (I'm nearly in need of a wig myself after that one).

If the age of the wig now is \( W \), the age of the judge now is \( 56 - W \).
Therefore, the age of the judge back then is \( W \) and the age of the wig back then is \( \frac{56 - W}{2} \).
The age difference of the wig then and now must match the age difference of the judge then and now.
So \( W - \frac{56 - W}{2} = (56 - W) - W \)

Simplify a wee bit by multiplying out brackets:
\( W - 28 + \frac{W}{2} = 56 - 2W \)

Double the whole thing to get rid of that pesky half:
\( 2W - 56 + W = 112 - 4W \)

Rearrange to get:
\( 7W = 168 \)
So \( W = 24 \).

The wig is 24 now and the judge is 32.

The rest of the clues, which describe the situation eight years ago, are easily verified from here! "

"This is my solution but I am not entirely confident 🙂

Now Judge age is \( x \) Wigs age is \( y \)

Then Judge age is \( y \) Wigs age is \( y \) – difference in judges ages = \( y – (x – y) = 2y – x \)

So \( x = 2(2y – x) \)

Hence \( x = 4y – 2x \)

So \( 3x = 4y \)

\( x = \frac{4y}{3} \)

Sum of ages now \( x + y = 56 \)

So \( \frac{7y}{3} = 56 \)

\( y = 24 \) Wig age now

\( x = 32 \) Judge age now "
