In a JRC one day camp, 150 gm of rice and 15 ml oil are needed for a student. If there are 40 students to attend the camp how much of rice and oil are needed?
उत्तर
Rice needed for one student = 150 g
Rice needed for 40 students = 150 g × 40
= 6000 g
= `6000/1000` kg
= 6 kg
Oil needed for one student = 15 ml
Oil needed for 40 students = 15 ml × 40
= 600 ml
= `600/1000` l
= 0.6 l
∴ For the camp 6 kg of rice and 0.6 l of oil needed.
