If `P = {A,B,C,D}` and `Q = {a,b,c,d}` then P and Q are `"______"` set (equal/equivalent)

If P={a,b,c} and Q={r},form the set P times Q

If P={a,b,c} and Q={r}, form the sets P xx Q and Q xx P . Check if the products are equal or not?

If P={a,b,c,d,e,f} and Q={a,c,e,f}," prove that "(P-Q) cup(PcapQ)=P

If P = {a , b , c} and A xxB = {(p , q), (p , r), (m , q), (m , r)} Q = {r} , form the sets P xxQ a n d Q xxP .Are these two products equal?

In A B C , P Q is a line segment intersecting A B at P and A C at Q such that P Q B C and P Q divides A B C into two parts equal in area. Find (B P)/(A B) .

If a ,b ,a n dc are in A.P. p ,q ,a n dr are in H.P., and a p ,b q ,a n dc r are in G.P., then p/r+r/p is equal to a/c-c/a b. a/c+c/a c. b/q+q/b d. b/q-q/b

If a ,b ,a n dc are in A.P. p ,q ,a n dr are in H.P., and a p ,b q ,a n dc r are in G.P., then p/r+r/p is equal to a/c-c/a b. a/c+c/a c. b/q+q/b d. b/q-q/b

If a ,b ,a n dc are in A.P. p ,q ,a n dr are in H.P., and a p ,b q ,a n dc r are in G.P., then p/r+r/p is equal to a/c-c/a b. a/c+c/a c. b/q+q/b d. b/q-q/b

If a ,b ,a n dc are in A.P. p ,q ,a n dr are in H.P., and a p ,b q ,a n dc r are in G.P., then p/r+r/p is equal to a. a/c+c/a b. a/c-c/a c. b/q + q/b d. b/q - q/b
