at a profit of 8 percent of shopkeeper sold a calculator for RS.1,382.40 . if he wants to increase his profit by 2 percent at what price should be sell the calculator?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
