a grocer has a sale of rs . 5255 , rs . 5840 , rs . 5921 , rs . 6022 and rs . 6499 for 5 consecutive months . how much sale must he have in the sixth month so that he gets an average sale of rs . 5500 ?
"total sale for 5 months = rs . ( 5255 + 5840 + 5921 + 6022 + 6499 ) = rs . 29537 . required sale = rs . [ ( 5500 x 6 ) - 29537 ] = rs . ( 33000 - 29537 ) = rs . 3463 . answer : b"
subtract(multiply(add(5, const_1), 5500), add(add(add(add(5255, 5840), 5921), 6022), 6499))
