Question

for meeting of 500 students 175 kg of rice is required for a week after 75 of rice has been used , let us find how long will remaining rice last for 400 students​

Answer 1

Answer:

4 days

Step-by-step explanation:

Given,

For 500 students and for a week quantity of rice required = 175 Kg

Then, rice left = 175 - 75 = 100 Kg

Then, by using unitary method, we get,

For 1 student for a week quantity of rice required = 100/500 Kg = 1/5 Kg

Then,

For 1 for a day, quantity of rice required = 1/(5 × 7) = 1/35

Now, for 400 students, 100 Kg rice will remain for = 400/100 = 4 days.

Hence, our answer = 4 days
