Question

Preeti bought $8\frac{1}{2}$ kg of sugar for Rs $148\frac{3}{4}$. Find the price of sugar per kg.

Answer 1

Cost of $8\frac{1}{2}$ kg of sugar = Rs $148\frac{3}{4}$
∴ Cost of 1 kg of sugar = Rs $\left(148\frac{3}{4}÷8\frac{1}{2}\right)$
= Rs $\left(\frac{595}{4}÷\frac{17}{2}\right)$
= Rs $\left(\frac{595}{4}\times \frac{2}{17}\right)$ = Rs $\left(\frac{35}{2}\right)$ = Rs $17\frac{1}{2}$

Hence, the cost of 1 kg of sugar is Rs $17\frac{1}{2}$.
