Question

(ii) lf in a piece of this alloy, carbon is 3 kg, what is the weight of the alloy piece?​

Answer 1

Given,

Quantity of Carbon in a Alloy piece = 3 kg

Let, the weight of Alloy piece be x kg

Then, according to the ques

⇒ 12 % of x = 3

⇒ $\frac{12}{100}$ ×  x = 3

⇒ 3 × $\frac{100}{12}$ = 25 g

Hence, the weight of the Alloy piece is 25 g.
