Question

Virendra bought 18 bags of rice, each bag weighing 5.250 kg. How much rice did he buy altogether? If the rice costs 42 rupees per kg, how much did he pay for it?

Answer 1

Weight of each bag of rice = 5.250 kg

Number of bags of rice bought = 18

∴ Weight of rice bought altogether = Weight of each bag of rice × Number of bags of rice bought

= 5.250 kg × 18

= ${\displaystyle \frac{525}{100}\times \frac{18}{1}}$

= ${\displaystyle \frac{525\times 18}{100\times 1}}$

= ${\displaystyle \frac{9450}{100}}$

= 94.5 kg

Rate of rice = ₹ 42/kg

∴ Total amount paid for the rice = Weight of rice bought altogether × Rate of rice

= 94.5 kg × ₹ 42/kg

= ${\displaystyle \frac{945}{10}\times \frac{42}{1}}$

= ${\displaystyle \frac{945\times 42}{10\times 1}}$

= ${\displaystyle \frac{39690}{10}}$

= ₹ 3,969

Thus, Virendra bought 94.5 kg of rice altogether and the total amount paid by him is ₹ 3,969.
