Question

example word problem in percentage sum

Answer 1

An alloy contains 26 % of copper. What quantity of alloy is required to get 260 g of copper?

Solution:

Let the quantity of alloy required = m g

Then 26 % of m =260 g

⇒ 26/100 × m = 260 g

⇒ m = (260 × 100)/26 g

⇒ m = 26000/26 g

⇒ m = 1000 g
