Question

The ratio between weights of gold and silver in an alloy is $17:3$. If the weight of silver in the alloy is $2.7gm$, find:

the weight of gold in the alloy

Answer 1

Given that the weight of silver in the alloy $=$ $2.7gm$

and also the ratio between weights of gold and silver in an alloy is $17:3$.

Assume weight of gold in the alloy $=xgm$

$$\begin{gathered} \frac{x}{2.7gm}=\frac{17}{3} \\ x=\frac{17\times 2.7gm}{3} \\ x=15.3gm \end{gathered}$$

Hence, the weight of gold in the alloy is $15.3gm$
