Problem: if the sales tax be reduced from 5 ( 1 / 3 ) % to 3 ( 1 / 2 ) % , then what difference does it make to a person who purchases a bag with marked price of rs . 5000 ?
Rationale: "explanation : required difference = ( 5 ( 1 / 3 ) of rs . 5000 ) - ( 3 ( 1 / 2 ) of rs . 5000 ) = ( 16 / 3 – 7 / 2 ) % of rs . 5000 = ( 11 / 6 ) x ( 1 / 100 ) x 5000 = rs . 91.66 answer d"
annotated_formula: subtract(multiply(add(divide(add(5, divide(1, 5)), const_100), 1), divide(5000, add(divide(add(divide(1, 2), 1), const_100), 1))), 5000)
