Answer 2

Answer:

The weight of zinc is 3 kg of the alloy is 1.8 kg. Find the weight if zinc in 10 kg of alloy?

direct and inverse proportion question...

Bro you need to do by yourself but i can give you example..

Step-by-step explanation:

Question

The ratio of copper and zinc in an alloy is 9:7. If the weight of zinc in the alloy is 9.8 kg, find the weight of copper in the alloy in kg.

Given,

Weight of zinc in the alloy = 9.8kg

The ratio of copper and zinc in an alloy = 9 : 7.

Let,

Weight of copper = 9x

Weight of zinc = 7x

9.8 = 7x

x = 1.4kg

∴ Weight of copper in the

alloy = 9x

= 9 (1.4)

= 12.6kg
