in a hostel , the number of students decreased by 12 % and the price of food increased by 20 % over the previous year . if each student consumes the same amount of food then by how much should the consumption of food be cut short by every student , so that the total cost of the food remains the same as that of the previous year ?
n0 = 12.0
n1 = 20.0
t0 = n1 + 100.0
t1 = 100.0 * 100.0
t2 = 100.0 - n0
t3 = t0 * t2
t4 = t1 / t3
t5 = 1.0 - t4
answer = t5 * 100.0
print(answer)
