Question : If $p^2+q^2=7pq$, then the value of $\frac{p}{q}+\frac{q}{p}$ is equal to:
Option 1: 9
Option 2: 5
Option 3: 7
Option 4: 3
Correct Answer: 7
Solution : Given: $p^2+q^2=7pq$ Divide the above equation by $pq$ on both sides, we get, ⇒ $\frac{p^2+q^2}{pq}=\frac{7pq}{pq}$ ⇒ $\frac{p}{q}+\frac{q}{p}=7$ Hence, the correct answer is 7.
Question : Directions: In the following question, a sentence is given with a blank that is to be filled in with an appropriate word. Four alternatives are suggested; choose the correct alternative out of them as your answer.
You must __________your career with all seriousness.

Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following 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.) (28, 65, 261) (37, 83, 342)
Option 1: (39, 42, 393)
Option 2: (46, 92, 414)
Option 3: (29, 54, 358)
Option 4: (78, 95, 485)
Correct Answer: (46, 92, 414)
Solution : Given: (28, 65, 261), (37, 83, 342)
(28, 65, 261); 261 – 65 = 196; 196 ÷ 7 = 28 (37, 83, 342); 342 – 83 = 259; 259 ÷ 7 = 37 Let's check the options – First option: (39, 42, 393);
Question : If $x \sin 45° = y\operatorname{cosec} 30°$, then $\frac{x^4}{y^4}$ is equal to:
Option 1: $4^3$
Option 2: $6^3$
Option 3: $2^3$
Option 4: $8^3$
Correct Answer: $4^3$
Solution : Given: If $x \sin \ 45° = y \operatorname{cosec} 30°$. $⇒\frac{x}{y} = \frac{\operatorname{cosec}30°}{\sin 45°}$ Substitute the values of the given trigonometric ratios, we get, $⇒\frac{x}{y} = \frac{2}{\frac{1}{\sqrt{2}}}$ $⇒\frac{x}{y} = (2\sqrt{2})$ On both sides of the above equation, taking the fourth power gives us, $⇒\frac{x^{4}}{y^{4}} =
Question : Two donkeys are standing 400 metres apart. The first donkey can run at a speed of 3 m/sec and the second can run at 2 m/sec. If two donkeys run towards each other, after how much time (in seconds) will they bump into each other?
Option 1: 60
Option 2: 80
Option 3: 400
Option 4: 40
Correct Answer: 80
Solution : Here the distance between two donkeys = 400 metres. Speed of the first donkey = 3 m/sec. Speed of the second donkey = 2 m/sec. If both running in opposite directions relative speed = (3 + 2) = 5 m/sec. So, the time taken to
Question : A unit price elastic demand curve will touch
Option 1: Both price and quantity axis .
Option 2: Neither price axis , nor quantity axis.
Option 3: Only price axis .
Option 4: Only quantity axis .
Correct Answer: Neither price axis , nor quantity axis.
Solution : The correct option is Neither price axis, nor quantity axis.
The price (vertical axis) or quantity (horizontal axis) axis will never be touched by a unit price elastic demand curve during its entire length. This implies that if a
