`x*y=x+y+1` and `2p*5p=50` then `p=`

If x= 3p and y=(2p)/5+1 , then find the value of p for which x = 5y.

In P=(5x+2y)/(3x-4y) , if x=5 and P=7, the y=?

IF y+x(2p+1)+3=0 and 8y-x(2p-1)-5=0 are perpendicular find p.

If P and Q are the points of intersection of the circles x^2+y^2+3x+7y+2p-5=0 and x^2+y^2+2x+2y-p^2=0 , then there is a circle passing through P, Q and (1, 1) for :

If y+ (2p + 1) x + 3=0 and 8y- (2p-1)x=5 are mutually perpendicular, find the value of p.

If X and Y be two events such that P(X//Y) = 1/2, P(Y//X) = 1/3 and P(X nnn Y) = 1/6 , then P(X uu Y) is

If 5x-y,2x+y,x+2y are in "A.P" and (x-1)^(2),xy+1,(y+1)^(2) are in G.P (x!=0) then x+y=
