Question : A number is greater than 58 times its reciprocal by $\frac{3}{4}$. What is the number?
Option 1: –8
Option 2: 12
Option 3: –12
Option 4: 8
Correct Answer: 8
Solution : Let the number be $x$. According to the question, $\frac{58}{x}+\frac{3}{4}=x$ $\Rightarrow 4x^2-3x-232=0$ $\Rightarrow 4x^2-32x+29x-232=0$ $\Rightarrow 4x(x-8)+29(x-8)=0$ $\Rightarrow (4x+29)(x-8) =0$ $\Rightarrow (4x+29)=0$ or $(x-8) =0$ $\therefore x=\frac{-29}{4},8$ Hence, the correct answer is 8.

Question : A man has some hens and some cows. If the total number of heads of both is 50 and the number of feet of both is 142, then the number of cows is:
Option 1: 21
Option 2: 25
Option 3: 27
Option 4: 29
Correct Answer: 21
Solution : Let's assume: h = number of hens c = number of cows From the problem, we can make two equations: 1) Each hen and each cow has one head: h + c = 50 ––(i) 2) Each hen has 2 feet and each cow has
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 - operations on 13 such as adding/subtracting/multiplying, etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (12, 8, 20) (7, 3, 15)
Option 1: (9, 4, 19)
Option 2: (10, 5, 45)
Option 3: (8, 5, 12)
Option 4: (11, 7, 17)
Correct Answer: (9, 4, 19)
Solution : Given: (12, 8, 20); (7, 3, 15)
The pattern is as follows – (12, 8, 20)→{(12 – 8) × 3} + 8 = {4 × 3} + 8 = 12 + 8 = 20 (7, 3, 15)→{(7 – 3) × 3} + 3
Question : How does La-Nina affect the Pacific Ocean?

Question : Simplify the following expression. $(4 x + 1)^2 - (4 x + 3)(4 x - 1)$
Option 1: $(4 x + 1)$
Option 2: $4$
Option 3: $(4x- 3)$
Option 4: $4x$
Correct Answer: $4$
Solution : $(4x + 1)^2 - (4x + 3)(4x - 1)$ $=16x^{2} + 1 + 8x-(16x^{2} -4x + 12x - 3)$ $=16x^{2} + 1 + 8x - 16x^{2} + 4x - 12x + 3$ $=4$ Hence, the correct answer is 4.
