If P= {5,6,8,10,12,} , Q = {0,3,6,9,12,15,8} and R = { 0,1,2,3, ….10 } Q cap R

If P= {5,6,8,10,12,} , Q = {0,3,6,9,12,15,8} and R = { 0,1,2,3, ….10 } n (P cap Q ) , n ( Q cap R) and n(P cap R)

If P= {5,6,8,10,12,} , Q = {0,3,6,9,12,15,8} and R = { 0,1,2,3, ….10 } P cap R

If origin is the centroid of the triangle with vertices P(3a, 3, 6), Q (-4, 2b, -8) and R(8, 12, 2c), then the value of a, b, and c are

If I vec(a) I = 4 and -3 le lamda le 2 ,then I lambda vec(a) I lies in (A) [0,12] (B) [2,3] (C) [8,12] (D) [-12,8]

If |vec(a) | = 4 and -3 le lamda le 2 ,then I lambda veca I lies in (A) [0,12] (B) [2,3] (C) [8,12] (D) [-12,8]

Find which of the are in proportion : 12,16,2, 8
