The product of `a\ a n d\ b` is added to their sum is written as `a b+a+b` (b) `a+b-a b` (c) `a+a b` (d) `a+a b-b`

The product of a\ a n d\ b is added to their sum is written as (a) a b+a+b (b) a+b-a b (c) a+a b (d) a+a b-b

The product of a and b is added to their sum is written as ab+a+b(b)a+b-aba+ab (d) a+ab-b

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

If a ,\ b ,\ c ,\ d are in proportion, then (a) a b=c d (b) a c=b d (c) a d=b c (d) None of these

If a\ a n d\ b are two numbers such that a b\ =\ 0 , then (a) a\ =\ 0\ a n d\ b\ =\ 0 (b) a\ =\ 0\ or\ b\ =\ 0 (c) a\ =\ 0\ a n d\ b!=0 (d) b\ =\ 0\ a n d\ a!=0

The sum of a\ a n d\ b is multiplied by taking away 5 from their sum. The expression representing the statement is: (a) (a+b)(a+b-5) (b) (a+b)(5-a-b) (c) (a+b)(5-a+b) (d) (a+b)(5+a-b)

If the first second and last term of an A.P. are a ,\ b ,\ a n d\ 2a\ respectively then its sum is a. (a b)/(2(b-a)) b. (a b)/(b-a) c. (3a b)/(3(b-a)) d. none of these

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

a\ a n d\ b are two co-primes. Which of the following is/are true? (a) LCM (a ,\ b)=\ a\*\ b (b) HCF (a ,\ b)=1 (c) Both (a)a n d\ (b) (d) Neither (a)\ n o r \ (b)

a, b are the real roots of x2+ px +1-0 and c, d are the real roots of 2 x + qx + 1 = 0 then (a-c)(h-c)(a + d)(b + d) is divisible by n) a+b+c+d (b) a +b-c-d (d) a -b-c-d (c) a-b+c-d
