Arjun and Bheem can do a piece of work in 8 and 10 days respectively. If they started the work together and worked on it for 3 days, then find the time taken by B alone to complete the remaining work.
ATQ, Let we can assume that the total work be 40 units Arjun ’s one-day work will be then= 5 units Bheem’s one-day work = 4 units Then, Work done by Arjun and Bheem together in 3 days = 9 x 3 = 27 days Therefore, the rest work will be = 40 – 27 = 13 units Hence, the required number of days will be = 13/4 = 3.25 days
