Question

A person spent Rs 3200 as cost of wheat for 30 days. If they spent Rs 2400 for 30 students,for how many days will the wheat last?

Answer 1

Rs 3200 for 30 students for 30 days  So  Rs per student per day = 3200/ 30 × 30  = 32/9  Rs 2400 for 30 students. Let the number of days it will last be x  32/9 = 2400/ 30 × x  x = 22 days and 12 hours  The per student per day cost should remain same.
