Answer 1

Answer:

Question:-

The ratio of zinc and copper in an alloy in 7:9. If the weight of copper in the alloy is 306 gram, calculate the weight of zinc.

Solution:-

Let the ratio be 7x : 9x

Weight of zinc = 7x

Weight of copper = 9x

⇒ 9x = 306

x = 306/9

x = 34

Weight of zinc = 7x

= 7(34)

= 238

Weight of zinc = 238 gram

Weight of copper = 306 gram
