1) If - X = 6 and = {1, 3} then, - is (A) 1 (B) 2 (C) 3 (D) 6 2) If the ordered pairs - + 2, 4 and - 5, 2 + are equal then - , is (A) - 2, −2 (B) - 5, 1 (C) - 2, 3 (D) - 3, −2 3) If is a relation from to , which of the following is correct? (A) = ∪ (B) = ∩ (C) ⊆ (D) ⊆ 4) Let - = and - = then the total number of relations that can be defined from A to B is (A) (B) (C) 2 − 1 (D) 2 5) Using Euclid’s division lemma, if the cube of any positive integer is divided by 9 then the possible reminders are (A) 0, 1, 8 (B) 1, 4, 8 (C) 0, 1, 3 (D) 1, 3, 5 6) If the HCF of 65 and 117 is expressible in the form of 65 − 117, then the value of is (A) 4 (B) 2 (C) 1 (D) 3 7) Given !" = 1, !# = 3 and !$ = !$%" + !$%# then !& is (A) 3 (B) 5 (C) 8 (D) 11 8) If , , ' are in A.P, then the value of (%) )%* = (A) ( ) (B) ) * (C) ( * (D) 1 9) The solution of the system + + , − 3+ = −6, −7, + 7- = 7, 3- = 9 is (A) + = 1, , = 2, - = 3 (B) + = −1, , = 2, - = 3 (C) + = −1, , = −2, - = 3 (D) + = 1, , = 2, - = −3 10) /0%/ 0 ÷ 20%2 /03 is (A) 40 2 (B) 405 - #"0%#" (C) #"03%6#07#" /05 (D) 2- 0 3%#07" 03 11) The quotient When 8 3%#& 87/ divided by 87& 8 3%4 is (A) - + − 5- + − 3 (B) - + − 5- + + 3 (C) - + + 5- + − 3 (D) - + + 5- + + 3 12) The square root of #&9 8:0 ;< => #& 8?0?< ? is equal to (A) "9 & @ 8 3< ; 03 @ (B) 16 @ 0 3 8 3< ; @ (C) "9 & @ 0 8​
