Answer:
Q can complete the work in 24 days
Step-by-step explanation:
P can complete the work= 12 days
P' one day work= 1/12 days
P and Q together can complete the work= 8 days
P and Q' one day work= 1/8
Q alone can complete the work=P+Q=P and Q
=1/2+Q= 1/8
=Q= 1/8–1/2
L.C.M= 24 =Q= 3/24–2/24
=Q= 1/24= 24days
