a trader marked the selling price of an article at 60 % above the cost price. at the time of selling, he allows certain discount and suffers a loss of 1 %. he allowed a discount of:
multiply(const_100, divide(add(multiply(add(const_2, const_3), const_2), 1), add(const_100, 60)))
"sol . let c . p . = rs . 100 . then , marked price = rs . 160 , s . p . = rs . 99 . ∴ discount % = [ 11 / 160 * 100 ] % = 6.8 % answer c"
