Question

A shopkeeper sells one transistor for Rs. 750 at a gain of 25% and another for Rs. 950 at a loss of 5%. His total gain or loss percent is:

• A. 5.71% gain
• B. 7.78% loss
• C. 6.25% gain
• D. 8.33% gain
• E. 8.33% loss

Answer 1

The correct option is A 5.71% gain

Profit from first transistor $=750-(\frac{750}{125}\times 100)=Rs.150$
Loss from the second transistor $=(\frac{950}{95}\times 100)-950=Rs.50$
Total profit = 150 – 50 = Rs. 100
Profit percentage $=\frac{100}{1000+750}\times 100=5.714\%$
