Question

If goods be purchased for Rs 450 and one third sold at a loss of 10%. At what gain percentage should the remainder be sold so as to gain 20% on the whole transaction?

• A. 32%
• B. 35%
• C. 28%
• D. 30%

Answer 1

Answer:

B. 35%

CP of total goods = Rs. 450. CP of one third goods = 1/3 × 450 = Rs. 150 CP of remaining 2/3 goods = 450 - 150 = Rs. 300 One third goods sold at a loss of 10% SP of one-third goods = 150 × 90/100 = Rs. 135 Gain 20% on the whole transaction. SP of total goods = 450 × 120/100 = Rs. 540 SP of remaining goods = 540 - 135 = 405 Gain% = (405 - 300)/300 × 100 = 105/3 = 35%
