Question

A shopkeeper purchased 200 bulbs for rupees 10 each. however 5 bulb were fused and had to be thrown away. the remaining were sold at rupees 12 each. find the gain or loss percent

Answer 1

200×10=2000=CO
5 bulbs fused means 100-5=95 bulbs left.
95 bulbs sold at Rs. 12 means 95×12=1140=SO
Loss= 2000-1140=Rs. 860
Loss%=loss/CP×100
860/2000×100
