Question 5
An alchemist was trying to mix three elements - copper, silver and gold - according to an
ancient recipe for making the "Philosopher's Stone". He mixed them in the ratio 5:7:9.
But on a closer look, he realised that they were actually supposed to be mixed in the ratio
9:7:5. Consequently, he decided to add X grams of copper and Y grams of silver to the
mixture to achieve the required ratio. What is X: Y?
1) 5:2
2) 5:1
3) 9:5
4) 2:1
