A, B and C can individually complete a piece of work in 30, 50 and 75 days respectively. They worked on one day each, with A starting the work followed by B the next day and C the next day. They continued working like this till the 30th day .

Means all worked for 10 days each in first 30 days.
They completed 2/3rd work in 30 days.
Balance 1/3 work is completed in 20 days by B and C working on alternate days with B working on 31st day. Each worked for 10 days.
