    P is thrice as efficient as Q and is therefore able to finish a piece of work in 60 days less than Q. Find the time in which P and Q can complete the work individually.

    A)  20 days and 60 days

    B)  30 days and 90 days

    C)  40 days and 120 days

    D)  None of the above

    Correct Answer: B

    Solution :

    Efficiency of P: Q = 3 :1 Required number of days of P: Q = 1:3 i.e., if P requires \[x\] days, then Q requires \[3x\] days. But         \[3x-x=60\] \[\Rightarrow \]   \[2x=60\] \[\Rightarrow \]   \[x=30\]            and       \[3x=90\] Thus, P can finish the work in 30 days and Q can finish the work in 90 days.
