The major product of the following reaction is: (A) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (C) (D) (D) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B) (B)

Which of the following statement is false: A-B=A nn B b.A-B=A-(A nn B) c.A-B=A-B' d.A-B=(A uu B)-B

Simplify: (a xx b) xx (a^(-1) + b^(-1) ) (a) a - b (b) a (c) a + b (d) b

For a reaction of the type Aa+bB rarr products ( -)(d[A])/(dt) is equal to (A) (-d[B])/(dt) (B) -(b)/(d)(d[B])/(dt) (C) -(a)/(b)times(d[B])/(dt) (D) -(b)/(a)times(d[B])/(dt)

In a triangle A B C , right angled at B , the inradius is (A B+B C-A C)/2 (b) (A B+A C-B C)/2 (A B+B C+A C)/2 (d) none

Which one of the following operations on sets is not correa where B' denotes the complement of B? a)(B'-A')U(A'-B')=(AUB)-(AnnB) b)(A-B)U(B-A)=(A'UB')-(A'nnB') c)(B'-A')n(A'-B')=(B-A)nn(A-B) d)(B'-A')n(A'-B')=(B-A')U(A'-B)

The product (B) is : a. b. c d.

If U=(a, b, c, d, e),A= (a, b, c) and B =(b, c, d, e), then verify (ii) (A n B)' (A' u B') (i) (A u B)' =(A' n B')

If a+b+c= 0 , then ((a+b)/(c ) + (b+c)/(a) + (c+ a)/(b)) ((c )/(a+b) + (b)/(a+c) + (a)/(b+c)) = ?

The area of the triangle formed by (a,b+c),(b,c+a) and (c,a+b) is a+b+c( b) abc(a+b+c)^(2)(d)0

If A and B are two sets,then (A-B)uu(B-A)uu(A nn B) is equal to A uu B( b) A nn B( c) A (d) B
