1. Product of any number with zero is 0

   Ans : C

2. 4 - 5 < c - d < 10 - 7

   -1 < c - d < 3

   3 > c - d

   Ans : A

3. Prime numbers are 2, 3, 5, 7, 11, 13, 17 and ... so on.
   b could be any of the above prime numbers.
   Given a = 7x - 2 where 7x is a multiple of 7.
   The relationship cannot be determined from the given data.

   Ans : D

4. In the given right angled triangle, (hypotenuse)² = The sum of the squares of the other 2 sides.

   (12 Ö 2 )² = 122 + ?²

   288 = 144 + ?²

   \ ?² = 144

   \ ? = 12

   Since this is an isosceles right triangle, a = 45

   Ans : C

5. Given t ¹0
   then there are two possibilities: i) Either t > 0 or ii) t < 0.

   If t > 0, suppose t = 3.
   Then t² + 2t = 8,
   and t² - 2t = 0.

   In this case, LHS > RHS.

   If t < 0, suppose t = -1.
   Then t² + 2t = -1,
   and t² - 2t = 3

   In this case, LHS < RHS.

   This means that from the given information we cannot determine the relationship between the two columns. Hence the choice is D.

   Ans : D

6. 2h = 2 p r

      r = 2h
           2p

      r = h / p

   2 l = 2 r

      r = l

   8 l = 8 r

   2h = 2 ´ r p

   2h = 6.28 r

   8 l > 2 h

   Ans : A
