a dishonest shopkeeper professes to sell pulses at the cost price, but he uses a false weight of 920 gm. for a kg. his gain is … %.
multiply(subtract(inverse(divide(920, multiply(multiply(add(const_4, const_1), const_2), const_100))), const_1), const_100)
"his percentage gain is 100 * 80 / 920 as he is gaining 80 units for his purchase of 920 units . so 8.69 % . answer : e"
