Product of any number with zero is 0
Ans : C

4  5 < c  d < 10  7
1 < c  d < 3
3 > c  d
Ans : A

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

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

Given t ¹0
then there are two possibilities: i) Either t > 0 or ii) t < 0.
If t > 0, suppose t = 3.
Then t^{2} + 2t = 8,
and t^{2}  2t = 0.
In this case, LHS > RHS.
If t < 0, suppose t = 1.
Then t^{2} + 2t = 1,
and t^{2}  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

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
