is 7:5. The shopkeeper sold the wooden chair for Rs. 1600, making a profit of 33(1/3)%. If he sells both the steel chair and the wooden chair at a 25% profit and ___% profit, respectively, he would earn a total profit of Rs. ___. A) 25%, Rs.720 B) 10%, Rs.540 C) 20%, Rs.600 D) 16%, Rs.612Solution
Answer: B CP of steel chair=7x CP of wooden chair=5x CP of a wooden chair=1600*100/133.33=1600*3/4=Rs.1200 CP of a steel chair=1200*7x/5x=Rs.1680 From option (A), 1680*25/100+1200*25/100=720 This satisfies the given condition From option (B), 1680*25/100+1200*10/100=540 This satisfies the given condition From option (C), 1680*25/100+1200*20/100=660 This does not satisfy the given condition From option (D), 1680*25/100+1200*16/100=612 This satisfies the given condition
