Priya bought 15kg of rice for Rs. 94 ½. What is the cost of 1kg of rice and also find the cost of 10kg of rice.

So cost of 1 kg of rice = $\frac{{\displaystyle \frac{189}{2}}}{15}=\frac{189}{30}=\mathrm{Rs}.6\frac{9}{30}$

Therefore the cost of 10 kg of rice = $\frac{189}{30}\times 10=\mathrm{Rs}.63$
