Question

An alloy contains 32% of Copper, 40% Zinc and the rest Nickel.Find in grams the
quantity of each of the contents in 1kg alloy

Answer 1

Answer:

In 100% an alloy contains 32% copper, 40% zinc and the rest nickel. So, if an alloy is increased ten times, the respective contains are also increased ten times. Hence, 1 kg of alloy contains copper 320g, Zinc 400g and Nickel 280g. So, the correct answer is “320g, Zinc 400g and Nickel 280g

Answer 2

Answer:

• ★ 280 g

Step-by-step explanation:

★ Given :

• An alloy contains 32% of Copper.

• 40% Zinc and the rest Nickel.

★ To Find :

• Find in grams the quantity of each of the contents in 1kg alloy.

★ Solution :

➨ The Quantity of alloy = 1 Kg = 1000g

➨ The percentage of copper in it 32 %

➨ The Percentage of zinc in it = 40 %

➨ The percentage of neckel in it = { 100 - ( 32 + 40 )} % = 28 %

➨ The Quantity of copper in the alloy = 32% of 1000 g

➨ ( 32 / 100 × 1000 ) g = 320g

➨ The Quantity of zinc in the alloy = 40% of 1000 g

➨ = ( 40 / 100 × 1000 ) g = 400 g

➨ The Quantity of nickle in the alloy = 28 % of 1000 g

➨ ( 28 / 100 × 1000 ) g = 280 g

★ Additional information :

• First assume any variable as the alloy and convert the given percentage in the form of decimals of the variable and then solve accordingly.

• Know that basic conversational relation and convert the units from one form to another.
