the daily consumption of rice in a hostel with 240 students is 12 KG find the consumption of rice is the number of student is reduced to 170
lesson name:- direct and inverse proportion

Answer 1

Answer:

8.5 kg

Step-by-step explanation:12 kg = 240 students

1 student=12 divided by 240

              =0.05kg

so 170 students= 0.05kg*170==8.5 kg

Answer 2

Answer:

8.5 kgs

Step-by-step explanation:

My advice is not to go by direct and inverse formulas . The question here is simplified as they are asking for 1 day so we just have 2 things to compare here kgs of rice and number of students.

Just find that 1 kg serves how many students which is = 240 / 12 = 20 students.

So, 1 kg is enough for 20 students

So, 170 people require = 170 / 20 = 8.5 kgs.
