AI explanation

Let the original price be 100. Prashant bought it for 90, which is 10% less than the original price. He sold it to Vartika at a 30% profit on his purchase price, so the selling price is 1.30 times 90, which equals 117. His profit on the original price is 117 minus 100, which is 17, meaning he earned a 17% profit.
