Select the correct answerTo do a certain work, the ratio of efficiency of A to that of B is 3 : 7. Working together, they can complete the work in 10.5days. They work together for 8 days. 60% of the remaining work will be completed by A alone in?Options5.5days6.5 days5 days4 days

when working alone A takes 24 more days than time taken by A and B together to finish certain work. If A is 50% more efficient than B, then find the time taken by B to finish the work alone.

Select the correct answerA and B together can finish a work in 5 days. If A works twice his efficiency they can finish the same work in 3 days. In how many days will A alone finish the work?Options5.4 days7.5 days6.6 days15 days

Select the correct answerThe ratio of the efficiencies of A, B and C is 4 : 5 : 3. Working together, they can complete that work in 25 days. A and C together will complete 35% of that work in?Options12 days18 days15 days10 days

A can do 2/5 of a work in 12 days while B can do 66 2/3% of the same work in 16 days. They work together for 10 days. B alone will complete the remaining work in?Options6498

A and B working together can complete a work in 10 days. If A works at half of his efficiency and B works at thrice of his efficiency, they can complete the work in 6 days. In how many days can A complete the work at his normal efficiency?
