a trader always 12% discount and sold a fan at a loss of rs 16 if he had sold it at 10% discount he will have gain rupees 20 for what price did he purchased the fan​

profit = 30number is the answer of that question answer sapai

You’re saying that the trader sold something at a small discount and lost money on the deal. But if he’d given a bigger discount, and so sold it at a lower price, he’d have made a profit. Sorry, I just don’t see how that is possible!

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
