Question

An alloy consists of zinc and copper in the ratio 4:5. How much copper is there in 56kg of alloy?

Answer 1

Answer

wight of zinc = 4x = 4*6 = 24 kg

wight of copper = 5x = 5*6 = 30 kg

step by step explained

let there wight = x

ratio of there = 4:5

total wight = 54 kg

acorrding to question -------

so, 4x + 5x = 54

= 9x = 54

= x = 54/9 = 6

so wight of zinc = 4x = 4*6 = 24 kg

, wight of copper = 5x = 5*6 = 30 kg

I hope it is useful for you.
