when a mobile is sold for rs . 24000 , the owner loses 40 % . at what price must that mobile be sold in order to gain 40 % ?
"60 : 24000 = 140 : x x = ( 24000 x 140 ) / 60 = 56000 . hence , s . p . = rs . 56,000 . answer : option b"
floor(multiply(divide(divide(divide(multiply(divide(multiply(24000, const_100), subtract(const_100, 40)), add(const_100, 40)), const_100), const_100), 40), const_2))
