A shopkeeper fixed the marked price of his radio to make a profit of 30 %. Allowing
15 % discount on the marked price, the radio was sold. What percent profit did he
make?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
