Q1. A trader purchased two colour televisions for a total of Rs. 35000. He sold one colour television at 30% profit and the other 40% profit. Find the difference in the cost prices of the two televisions if he made an overall profit of 32%?
Answer: Rs. 21000
Explanation: Let cost of TV1 = x; overall profit equation 0.30x + 0.40(35,000 − x) = 0.32 × 35,000 solves to x = Rs. 28,000; difference = 28,000 − 7,000 = Rs. 21,000.
