Question
Anil sold 12 cameras at a loss of 10%. If he had sold
all the cameras for Rs. 1440 more, his overall profit would have been 20%. What is the cost price of 8 cameras?Solution
 Let the cost price of each camera be Rs. c.  Initial selling price of all cameras = 0.9 × 12 × c = Rs. 10.8c  According to the question, 10.8c + 1440 = 1.2 × 12c Or, 14.4c - 10.8c = 1440 Or, 3.6c = 1440 Or, c = 400 Therefore, the cost price of 8 cameras = 8 × c = Rs. 3200
