Read Solution (Total 1)

Answer is 13

since p is 30% more efficient than Q. so ratio of their efficiency, P:Q= 13:10
P can complete the work in 23 days. So work done by P alone in 23 days = time * efficiency = 13 x 23 = 299
P and Q's 1 day work = 13 + 10 = 23
time needed by P and Q together to complete the work = 299/23 = 13 DAYS.
