Correct Answer: 3, 2, 4, 5, 1

Solution : Given:
1. Flint 2. Flec 3. Flaw  4. Fleet 5. Flight

Step 1: Compare the first and second letters of each word. Since all the words start with the same letter F and are followed by l, then move on to the next letter.
Step 2: The third letter of each word is a, e, or i. Based on the alphabetical order of these letters, we can arrange them – Flaw, Flec, Fleet, Flint, Flight
Step 3: Compare the fourth letter of (Flec, Fleet). Flec will come before Fleet in the sequence as c comes before e in the alphabetical system. 
Step 4: Compare the fourth letter of (Flint, Flight). Flight will come before Flint in the sequence as g comes before n in the alphabetical system.

So, the sequence is Flaw, Flec, Fleet, Flight, Flint, or 3, 2, 4, 5, 1. Hence, the third option is correct.

Correct Answer: 125

Solution : Given:
64 × 8 ÷ 24 – 5 + 3 = ?

On interchanging the mathematical sign, we get –
= 64 ÷ 8 + 24 × 5 – 3
= 8 + 24 × 5 – 3
= 8 + 120 – 3
= 125

So, 125 is the required answer. Hence, the second option is correct.

Correct Answer: Rs. 400; Rs. 500

Solution : The monthly income of two persons is in the ratio 4 : 5 and their expenditures are in the ratio 7 : 9.
Let the monthly income of one person be 4$x$ and that of another be 5$x$,
Let the monthly expenditure of one person be 7$y$ and that of another be 9$y$.
According to the question,
$4x-7y=50$ .........................(1)
$5x-9y=50$ ..........................(2)
Solving these equations we get,
$x=100$ and $y= 50$
So, the income of one person $=4×100=400$
and the income of another person $=5×100=500$
Hence, the correct answer is Rs. 400; Rs. 500.

Correct Answer: Goat

Solution : The correct option is Goat.

Goats are well-suited to hot and dry environments due to their capacity to endure relatively high temperatures. They have physiological adaptations and behaviours that help them deal with the summer heat, such as the capacity to save water and control body temperature by panting and finding shade.

Correct Answer: 9

Solution : According to the question,
⇒  $x^2+8 y^2-12 y-4 x y+9=0$
⇒ $x^2 - 4xy + 4y^2 + 4y^2 - 12y + 9 = 0$
⇒ $(x - 2y)^2 + (2y - 3)^2 = 0$
⇒ $x - 2y = 0, 2y - 3 = 0$
⇒ $x = 2y, 2y = 3$
⇒ $x = 3, y = \frac{3}{2}$
Now, $7x - 8y$ = 7 × (3) – 8 × $\frac{(3)}{2}$
 = 21 – 12
= 9
Hence, the correct answer is 9.

Correct Answer: consecutive

Solution : The fourth option is the correct answer.

Subsequent specifically implies coming after something else in time or order, indicating a chronological sequence.

On the other hand, consecutive also denotes a sequence of events occurring one after the other without interruption.

The meanings of the other options are as follows:

• Prior means existing or occurring before in time; earlier.
• Preceding means coming before in time or order; going before.
• Antecedent refers to something that comes before; a preceding event or circumstance.

Therefore, the correct answer is consecutive.

Correct Answer: 36

Solution : Let the numbers be $4x$ and $5x$.
According to the question,
$\frac{4x+4}{5x+4}=\frac{5}{6}$
$⇒24x+24=25x+20$
$⇒x=4$
Thus, the numbers are 16 and 20.
So, the sum of the numbers = 16 + 20 = 36
Hence, the correct answer is 36.

Correct Answer: Increases

Solution : The correct option is to increase.

The round hole in the centre of a metal plate enlarges when the plate is heated. The following causes account for this:
The molecules along the rim of the hole and all the other component molecules vibrate more when the metal plate is heated. The metal plate expands as a result of the molecules along the rim of the hole.

Correct Answer: 0

Solution : Given: The number is 246p48.
Taking the last 3 digits = p48
For the least value of p, putting p = 0, the number 048 is divisible by 8.
$\therefore$ 246048 is also divisible by 8.
Hence, the correct answer is 0.

Correct Answer: Part III

Solution : The correct option is Part III.

Part III of the Indian Constitution is often referred to as the "Magna Carta of India." It contains the fundamental rights guaranteed to the citizens of India. These fundamental rights are considered essential for the protection of individual liberties and form a crucial aspect of the constitutional framework. These rights are justiciable, meaning citizens can seek legal remedies if they believe their fundamental rights have been violated.
