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.You need to login to perform this action.
