If `n(P) = 20, n(Q) = 18` and `n(Puu Q) = 27`, then `n(P - Q) = `

If n(PnnQ) = 23, n(PuuQ) = 57 and n(Q-P) = 26 , then n(P -Q) = "_____" .

If two sets P and Q ,n(P)=5 ,n(Q)=4 then n(P xx Q)=

If P and Q are two sets such that n(PcupQ) =75, n(Pcap Q) =17, and n(P) =49 , find n(Q) .

Find (PxxQ) , if n(Q-P)=10 and n(P-Q)=13 and n(PcapQ)=8 .

If (P-Q)=x+37,n(Q-P)=30+3x,n(P uu Q)=120+2x and n(P nn Q)=35, then x is:

Let P and Q be two sets such that n(P uu Q) = 70 ,n (P )= 45 and n(Q) = 38, Draw a Venn diagram and find : n(P-Q)

Let P and Q be two sets such that n(P uu Q) = 70 ,n (P )= 45 and n(Q) = 38, Draw a Venn diagram and find : n(Q- P)
