1. a * b     =     a² - ab

   3 * (-5)   = 3² - (3) (-5)

       = 9 + 15

       = 24

   - 5 * (3) = (-5)² - (-5) (3)

       = 25 + 15

       = 40

   24 < 40

   Ans : B

2. The series is as follows

   -3, 3, -6, 6, -9, 9, -12, 12, -15, 15, -18, 18, -21, 21, -24, 24, -27, 27, -30, 30

   t₇ ´ t₆ = (-12) ´ 9 = -108

   t₁₁ ´ t₄ = (-18) ´ 6 = -108

   Ans : C

3. t₁₁ + t₁₂ + t₁₃+ t₁₄ = -18 + 18 + (-21) + 21 = 0

t₃ + t₄ + t₅ + t₆ + t₇ = - 6 + 6 + (- 9) + 9 + (-12) = -12

 

     0 > -12

Ans : A
