A merchant sells his two cars one at 15% loss and another at 12% profit. If the cost prices of the two cars are in the ratio of 1:2, what is his percent profit or loss?

3% loss

3% profit

5% profit

5% loss

Explanation:

CP are in the ratio 1:2
Then let the CPs be Rs.100 & Rs.200 respectively,
1st SP = 100-15% of 100 = Rs.86.
2nd SP = 200 + 12% of 200 = Rs.224.
Total CP = Rs.300.
Total SP = 85+224 = Rs.309.
Profit = Rs.309-300 = Rs.9.
Profit percent = 9×100/300 = 3% profit.

Hence, option 2 is the correct answer.
