Question

One kg of rice costs Rs 42.65. What will be the cost of 18.25 kg of rice?

Answer 1

Price of 1 kg of rice = Rs. 42.65

Price of 18.25 kg of rice = Rs. 42.65 $\times$ 18.25
= $$\begin{gathered} \frac{4265}{100}\times \frac{1825}{100} \\ =\frac{7783625}{10000} \end{gathered}$$

= 778.3625

Thus, 18.25 kg of rice will cost Rs. 778.36.
