Question

An alloy contains 60% of copper and rest is zinc what is amount of zinc in 150 kg of alloy ​

Answer 1

Step-by-step explanation:

Copper = 60%

Then, Zinc = 100% - 60% = 40

Zinc in 150kg = 150 x 40% = 150 x 0.4 = 60kg

Answer 2

The amount of zinc is 90 kg

Step-by-step explanation:

Given : Amount of copper in an alloy = 60 %

To find: The amount of zinc

Now as given in question we have 150 kg of allow

Therefore

Amount of copper = $60\% \text { of total alloy}$

$Copper = \dfrac{60}{100} \times 150= 90 kg$

Amount of zinc = Total alloy - Amount of copper

                         = 150 kg - 90 kg = 60 kg

Hence, the amount of zinc is 90 kg
