Correct Answer: 3, 6, 5, 1, 2, 4

Solution : Given:
1. Strident 2. Student 3. Shirking 4. Stuffy 5. Spider 6. Spawn

Step 1: Compare the first letter of each word. Since all the words start with the same letter S, then move on to the next letter.
Step 2: The second letter of each word is t, t, h, t, p, p. Based on the alphabetical order of these letters, we can arrange them – Shrinking, Spider, Spawn, Strident, Student, Stuffy.
Step 3: Compare the third letter of (Spider, Spawn) and (Strident, Student, Stuffy). Spawn will come before Spider in the sequence as a comes before i in the alphabetical system. Similarly, Strident will come before Student and Stuffy as r comes before u.
Step 4: Compare the fourth letter of (Student, Stuffy). Student will come before Stuffy in the sequence as d comes before f in the alphabetical system.

So, the sequence is Shrinking, Spawn, Spider, Strident, Student, Stuffy, or, 3, 6, 5, 1, 2, 4. Hence, the first option is correct.

Correct Answer: 38.89%

Solution : Let the selling price (SP) be $x$
Cost price = $\frac{72}{100}\times x$
Now, the profit percentage
= $\frac{\text{Selling price – Cost price}}{\text{Cost price}}×100$
= $\frac{x-\frac{72}{100}x}{\frac{72}{100}x}\times 100$
= $\frac{\frac{28}{100}x}{\frac{72}{100}x}\times 100$
= $38.89\%$
Hence, the correct answer is 38.89%

Correct Answer: 104

Solution : Given: The sum of the first 13 terms and the first term is –10 and the last term is 26.
By using the formula, S_n = $\frac{n}{2}[a+l]$
Where $a$ is the first term, $l$ is the last term of the A.P., and $n$ is the number of terms.
By putting the values of 1^st and last term, we get,
⇒ S₁₃ = $\frac{13}{2}$[–10 + 26]
⇒ S₁₃ = $\frac{13}{2}$[16]
$\therefore$ S₁₃ = 13 × 8 = 104
Hence, the correct answer is 104.

Correct Answer: (1)

Solution : The sentence can be improved using the first option.

The first option is the correct choice as it provides the appropriate adverb attentively to describe how the listener should listen. Attentively means paying attention to and focusing on something, which fits the context of the sentence.

Hence, the correct answer is 197.5.

Correct Answer: 6, 3, 1, 2, 4, 5

Solution :  Given:
1. Strategy 2. Strength 3. Stranger 4. Stretch 5. Struggle 6. Strange

Step 1: Compare the first letter of each word. Since all the words start with the same letter S, we move on to the next letter.
Step 2: Let's move to the second letter of each word. Since all the words have the same second and third letters t and r, we move on to the next letter.
Step 3: The fourth letter of each word is: a, e, a, e, u, a. Based on the alphabetical order of these letters, we can arrange them: Strategy, Strength, Stranger, Stretch, Struggle, Strange.
Step 4: Compare the next letter of (Strategy, Stranger, Strange) and (Strength, Stretch). Strength will come before Stretch in the sequence as n comes before t in the alphabetical system.
Step 5: Compare the next letter of (Stranger, Strange). Strange will come before Stranger in the sequence as all the letters of the word Stranger are the same as Strange.

So, the sequence is Strange, Stranger, Strategy, Strength, Stretch, Struggle or 631245. Hence, the fourth option is correct.

Correct Answer: 3

Solution : For a number to be divisible by 8, the last 3 digits should be divisible by 8.
In the given number 89476*2, the last 3 digits are 6*2.
Since we have to find the smallest number with the given condition, we start substituting * with 0 to 9 and check if it is divisible by 8.
602 is not divisible by 8.
612 is not divisible by 8.
622 is not divisible by 8.
632 is divisible by 8.
Hence, the correct answer is 3.

Correct Answer: 4% loss

Solution : Given, a tradesman marks his goods 20% above his cost price.
Also, Discount given = 20%
Let Cost Price, CP = Rs. 100
Marked Price, MP = Rs. 120
Now, Discount = 20% of MP = $\frac{20}{100}×120$ = Rs. 24
Selling Price, SP = MP – Discount = Rs. (120 − 24) = Rs. 96
Loss percentage = $\frac{\text{CP – SP}}{\text{CP}}\times100$ = $\frac{100-96}{100}×100$ = 4%
Hence, the correct answer is a 4% loss.
