in a office work is distribute between p persons . if 1 / 7 members are absent then work increased for each person is ?
"let total % of work is 100 % total person = p 1 / 7 person are absent of total person . so absent person is 1 / 7 p ie p / 7 . left person is , p - p / 7 = 6 p / 7 . p person do the work 100 % 1 person do the work 100 * p % 6 p / 7 person do the work ( 100 * p * 7 ) / 6 p % = 116.67 % work increased for each person is = ( 116.67 - 100 ) % = 16.67 % answer : d"
subtract(divide(multiply(const_100, 7), subtract(7, 1)), const_100)
