pls tell like a word problems answers​

Answer 1

Answer:

1. Wheat = 250 g

2. Rice = 100 g

3. Pulses = 100 g

4. Sugar = 75 g

To find:

How much commodity has to be bought to serve 145 students a day.

Proof:

Total consumption of wheat by 145 students = 145*250 g = 36250 g

36250 g = 36.25 Kg of wheat.

Total consumption of rice by 145 students = 145* 150 g = 21750 g

21750 g = 21.75 Kg of rice.

Total consumption of pulses by 145 students = 145 * 100 g = 14500 g

14500 g = 14.5 Kg of pulses.

Total consumption of sugar by 145 students =

145 * 75 g = 10875 g

10875 g = 10.875 Kg of sugar.

Hence the above underlined weights are the amount of commodity required for purchasing.
