Q4. Work done by A, B, C and D is in arithmetic progression. C worked for 9 days and completed 30% work. A and B worked for 2 days and 3 days only. Find for how many days ‘D’ work to complete the remaining work if all four together can complete that work in 4 days.
(a) 12 days
(b) 10 days
(c) 8 days
(d) 6 days
(e) 4 days
Directions (5-5): A is twice efficient than B and B take 8 more days than C to complete a work. A took the contract to complete the same work in 6 days. 2 days later, he realized that he alone could only complete 60% work in given time period. So, he asked for help, B and C joined him for last 3 days and the work was completed on time.
Q5. Find the number of days taken by B and C to complete the same work.
(a) 7 days
(b) 7.5 days
