Q:

Arguments:

I. Yes. Safety of the country is of prime importance.

II. No. During peace, this money could be used for the development of the country.

A) Only argument I is strong	B) Only argument II is strong
C) Neither I nor II is strong	D) Both I and II are strong

Answer & Explanation Answer: A) Only argument I is strong

Explanation:

Clearly, defence is necessary for the safety of the country, which is of prime importance. So, argument I holds. Also, a country can concentrate on internal progress and development only when it is safe from external aggressions. So, argument II does not hold.

Q:

(3x + 2) (2x - 5) = ax² + kx + n .

What is the value of a - n + k ?

A) 5	B) 8
C) 9	D) 10

Answer & Explanation Answer: A) 5

Explanation:

This is a quadratic equation. To find n we multiply the last terms in each bracket together (2 times -5) = -10

To find ‘a’ we multiply the first terms in each bracket together (3x times 2x) = 6x2, So a = 6.

Thus a - n = 16

To find k we multiply the first term in the first bracket by the second term in the second bracket and add the result to the product of the second term in the first bracket and the first term in the second. (-15x + 4x) = -11x. So k = -11

16 - 11 = 5

Q:

The first term in a sequence is 1 and the second term is 5. From the third term on each term is the average (arithmetic mean) of all preceding terms. What is the 25th term in the sequence?

A) 2.5	B) 3
C) 5	D) 2.5

Answer & Explanation Answer: B) 3

Explanation:

Start constructing the sequence until you see the pattern

1...5...(average of 1 and 5 = 3)...(average of 1, 5, and 3 = 3)...(average of 1,5,3 and 3 = 3)

now you can see that all subsequent terms will be 3
