A and B can together complete a task 40 days. They worked together for 30 days and then B left. A finished the remaining task in next 22 days. In how many days A alone can finish the task?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 88 days
A and B can together complete a task 40 days.
In 30 days they both will complete 30/40 i.e 3/4 part of work.
Remaining work = 1 - 3/4 = 1/4 part
A finished the remaining task in next 22 days.
A finished the 1/4 part in 22 days.
A alone will complete the whole work in 22 × 4 = 88 days.
