Question

A piece of alloy weighing 80grams consists of 60grams of copper and the remaining is zinc. The ratio of copper to zinc is…
a) 3:2 b) 3:4 c) 3:1​

Answer 1

Given ,

• Weight of the alloy→ 80 grams
• Weight of copper → 60 grams

So, weight of zinc

= 80 - 60

= 20 gram .

Now , the ratio of copper to zinc

= 60 : 80

$\large= \frac{60}{80}$

$\large{ = \frac{3}{4} }$

$\large{ = \bold{ 3 \: : 2}}$
