the shopkeeper increased the price of a product by 25 % so that customer finds it difficult to purchase the required amount . but somehow the customer managed to purchase only 76 % of the required amount . what is the net difference in the expenditure on that product ?
n0 = 25.0
n1 = 76.0
t0 = n0 + 100.0
t1 = 100.0 * 100.0
t2 = n1 * t0
t3 = t1 - t2
t4 = t3 * 100.0
answer = t4 / t1
print(answer)
