Question

An alloy consists of copper and zinc. It contains 60% copper and the rest is zinc. Find the
quantity of copper and zinc in 425 g of this alloy.​

Answer 1

Answer:

copper = 60%

zn. = 40%

wt of alloy=425g

wt. of Cu= 425x60/100 = 255g

wt. of Zn=425x40/100 = I70g

Answer 2

Answer:

Question:-

An alloy consists of copper and zinc. It contains 60% copper and the rest is zinc. Find the

quantity of copper and zinc in 425 g of this alloy.

Solution:-

percentage of copper = 60%

percentage of zinc = ( 100 - 60 )%

= 40%

weight of alloy = 425 g

weight of copper = 60/100×425

= 255 g

weight of zinc = 40/100×425

= 170 g

Quantity of copper = 255 g

Quantity of zinc = 170 g
