"explanation : required difference = ( 4 ( 1 / 5 ) of rs . 5400 ) - ( 3 ( 1 / 4 ) of rs . 5400 ) = ( 21 / 5 – 13 / 4 ) % of rs . 5400 = ( 19 / 20 ) x ( 1 / 100 ) x 5400 = rs . 51.30 answer e"
subtract(multiply(add(divide(add(4, divide(1, 4)), const_100), 1), divide(5400, add(divide(add(divide(1, 4), 1), const_100), 1))), 5400)
