Question

The ratio of copper and zinc in an alloy is 7:8 . if the weight of copper is 8.4 kg, find the weight of zinc in the alloy.​

Answer 1

Answer :-

Given :-

• Ratio of copper and zinc = 7:8
• Weight of copper = 8.4 kg

To Find :-

• Weight of zinc in alloy

Solution :-

It is given that, ratio of copper to zinc is 7:8 in the alloy. So,

Let the weight of copper be 7x

Weight of zinc be 8x

We are also given that, weight of copper is 8.4 kg. Hence,

→ 7x = 8.4

→ x = 8.4 / 7

→ x = 1.2

So, weight of zinc = 8x

Weight of zinc = 8 × 1.2 = 9.6

Weight of zinc in the alloy is 9.6 kg
