A. 15/17% loss
B. 5 15/17% gain
C. 2/3% gain
D. None of these
Answer:B
A shopkeeper sells one transistor for Rs. 840 with a 20% profit and another for Rs. 960 with a 4% loss. His total gain or loss is calculated as follows:
A. 15/17% loss B. 5 15/17% gain C. 2/3% gain D. None of these
Explanation: 1st transistor C.P. = Rs. 100 /120x 840 = Rs. 700.2nd transistor C.P. = Rs. 100/96 x 960 = Rs. 1000.As a result, the total C.P. equals Rs. (700 + 1000) = Rs. 1700.S.P. total = (840 + 960) = Rs. 1800.Gain Percentage = 100/1700 x 100% = 5 15/17 Percentage.
