Question

An alloy contains 64% of zinc. How many kg of alloy is required to get 372 kg of zinc​

Answer 1

Answer:

581.25 kg

Step-by-step explanation:

Let the weight of alloy be x

Percentage of zinc in alloy = 64%

weight of zinc = 372 kg

weight of alloy required = 64/100 × x = 372

                                        = x = 372 × 100/64

                                        = x = 93 × 25/4

                                        = x = 23.25 × 25

                                        = x = 581.25 kg

∴ 581.25 kg of alloy is required to get 372 kg of zinc​
