A reduction of 20% in the price of sugar enables a purchaser to obtain 4 kg more for Rs. 160. What is the original price per kg? MCQ with Answer and Explanation

Explanation:
Total Cost Price = (26 * 20) + (30 * 36) = 520 + 1080 = 1600. Total quantity = 56 kg. Total Selling Price = 56 * 30 = 1680. Profit = 80. Profit percentage = (80 / 1600) * 100 = 5%.

Explanation:
Let original price = P. Reduced price = 0.8P. (400 / 0.8P) - (400 / P) = 5. (500 / P) - (400 / P) = 5. 100 / P = 5. P = 20.

Explanation:
CP=100, MP=120, SP=120*0.9=108, profit=8%.
