Question

An alloy contains 17% zinc, 28% tin and the rest is iron. Find the quantity of iron in 2 kg of this alloy

• A. 1.2 kg
• B. 1.1 kg
• C. 1 kg
• D. 0.9 kg

Answer 1

The correct option is B

1.1 kg

Percentage of Zinc + tin = 17 + 28 = 45%

$\therefore$ Percentage of iron = 100 - 45 = 55%

Quantity of iron in 2 kg of alloy = $\frac{55}{100}\times 2$ = $\frac{110}{100}$ = 1.1 kg
