"explanation : required difference = ( 4 ( 1 / 3 ) of rs . 8000 ) - ( 2 ( 1 / 2 ) of rs . 8000 ) = ( 13 / 3 – 5 / 2 ) % of rs . 8000 = ( 11 / 6 ) x ( 1 / 100 ) x 8000 = rs . 146.66 answer : b"
subtract(multiply(add(divide(add(4, divide(1, 4)), const_100), 1), divide(8000, add(divide(add(divide(1, 2), 1), const_100), 1))), 8000)
