Question
P, Q and R together can complete a work in 12 days. All
of them worked together for 6 days and then P left. How much time will Q and R together take to complete the remaining work? Statement I: If P completes a work in X number of days, then Q and R together complete the work in X number of days. Statement II: After leaving the work, P completed another work in 10 days.Solution
From statement I, it is clear that had P not left the work, the remaining work would have been completed in 6 days. Now since, P’s efficiency is equal to (Q + R)’s efficiency, now the work will completed in 12 days. Statement II is not related to the question.
