Question :- In an alloy, copper and zinc are mixed in a ratio 5:3 by weight. If weight of a block of alloy is 4.8 kg, find the weight of copper in it. ?
Solution :-
Let us Assume that, Copper and zinc mixed in the alloy are 5x kg and 3x kg.
Than,
→ Total weight of a block of alloy = Copper + Zinc
Putting values we get,
→ 5x + 3x = 4.8
→ 8x = 4.8
Dividing both sides by 8, we get,
→ x = 0.6kg.
Therefore,
→ weight of copper = 5x = 5 * 0.6 = 3 kg. (Ans.)
