Question

The ratio of copper and zinc in an alloy is 9:5. If the weight of copper in an alloy is 48.6 grams, find the weight of zinc in an alloy.​

Answer 1

Answer:

25.5 gram

Step-by-step explanation:

ratio of copper and zinc in alloy = 9:5

weight of copper = 48 g

let x be the weight of zinc

therefore 9/5= 48/x

9x = 5/48

x= 240/9

x = 25.5 g

Answer 2

Answer:

Given , Ratio of copper and zinc is 9 :5

Given Weight of Copper is 48.6 gms. Let, weight of zinc be x

Using Proportionality

9 : 5 : : 48.6 : x

Here product of means = product of extremes

( 5 × 48.6 ) ÷ 9 = 27 gms

Therefore , Weight of zinc is 27 gms
