Correct Answer: $30 \frac{5}{8} \%$

Solution : Share of marks obtained in English = $52^{\circ}$
Share of marks obtained in S.S. = $59^{\circ}$
Share of total marks obtained in English and S.S = $52^{\circ}$+$59^{\circ}$ = $111^{\circ}$------------(i)
Share of marks obtained in Hindi = $72^{\circ}$
Share of marks obtained in Maths = $88^{\circ}$
Share of total marks obtained in Hindi and Maths = $160^{\circ}$ -----------(ii)
Difference in share of marks = $160^{\circ}$–$111^{\circ}$ = $49^{\circ}$
Marks obtained in English and S.S. are less than marks obtained in Hindi and Maths by:
= $\frac{49}{160}×100$
= $30\frac{5}{8}$%
Hence, the correct answer is $30\frac{5}{8}$%.

Correct Answer: 6.6

Solution :
Given:
In triangle MNO, AB is parallel NO and MA = 2.5, AN = 7.5, MB = 2.2
Here, triangles MNO and MAB are similar because angle M in triangle MNO is equal to angle M in triangle MAB.
So, $\frac{MA}{MN}=\frac{MB}{MO}$
⇒ $\frac{2.5}{2.5+7.5}=\frac{2.2}{MO}$
$\therefore MO=8.8$
BO = MO – MB = 8.8 – 2.2 = 6.6
Hence, the correct answer is 6.6.

Correct Answer: Basketball in 2020

Solution : In 2018,
Basketball: 46 + 34 = 80
Football: 42 + 37 = 79
Cricket: 45 + 35 = 80
In 2019,
Basketball: 40 + 41 = 81
Football: 44 + 38 = 82
Cricket: 42 + 32 = 74
In 2020,
Basketball: 43 + 40 = 83
Football: 40 + 32 = 72
Cricket: 44 + 38 = 82
In 2021,
Basketball: 37 + 44 = 81
Football: 43 + 25 = 68
Cricket: 34 + 28 = 62
In 2022,
Basketball: 34 + 41 = 75
Football: 41 + 32 = 73
Cricket: 41 + 39 = 80
It can be seen that in the year 2020, Basketball has the maximum enrollment.
Hence, the correct answer is Basketball in 2020.

Correct Answer: confirm

Solution : The second option is the correct option. The word "confirm" is the most appropriate choice in this context because it means to establish the truth or correctness of something, which is exactly what the physician does with the blood test – they determine whether or not the woman is pregnant.

Term: It typically refers to a specific period

Confer: "Confer" means to grant or bestow something, such as an honour or title, upon someone.

Firm: stronghold or belief in something or someone. All these don't fit in the context.

So the correct sentence is "With a blood test, a physician was able to confirm the woman's pregnancy."

Correct Answer: Adept, demonstration

Solution : The correct choice is the fourth option, "adept, demonstration".

"Adept" and "demonstration" fit perfectly in the sentence. "Adept" means highly skilled or proficient at something and "demonstration" refers to a display or exhibition of how something is done. This helps in conveying the intended meaning that he was so skilled at his job that he was asked to show the visitors how it was done.

The meanings of the other options are as follows:

• "Able" is someone who can do something.
• "Disclosure" means the sharing of information or secrets.
• "Agile" means able to move quickly and easily.
• "Demolition" is the breaking and destroying of structures.
• "Accurate" is something that is correct and precise.
• "Display" is showing or presenting something.

Therefore, the complete sentence is "He was so adept at his job that he was asked to give a demonstration to the visitors".

Correct Answer: To control the level of sugar in the body

Solution : The correct option is - To control the level of sugar in the body.

The pancreatic islets of Langerhans cells generate insulin, a peptide hormone that regulates carbohydrate, lipid, and protein metabolism and promotes cell division and growth through its mitogenic effects.

Insulin helps cells absorb glucose, regulates carbohydrate, lipid, and protein metabolism, and keeps blood sugar levels normal.

Correct Answer: productive

Solution : The correct choice is the fourth option.

Explanation: The term productive means achieving or producing results, which fits well with the context of evaluating social media use. It suggests assessing whether the use of social media contributes to positive and meaningful outcomes.

Therefore, the correct word to fill in the blank (4) is productive.

Correct Answer: 318

Solution : Given:
333, 321, 328, 328, 323, 335, ?

Subtract 5 and add 7 alternatively to each term to get the next alternate term in the series –
333 – 5 = 328; 321 + 7 = 328; 328 – 5 = 323; 328 + 7 = 335; 323 – 5 = 318

Therefore, 318 is the missing number of the series. Hence, the third option is correct.

Correct Answer:

Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection.
Here, according to the information provided, the mirror is placed on the right side of the figure (on line MN). So, the left side of the reflected image will appear as the right side, and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same.
Thus, the correct mirror image of the given figure will be –

Hence, the fourth option is correct.

Correct Answer: 4

Solution : Given:
+ means –, × means +, – means ÷, and ÷ means ×
72 × 19 ÷ 13 + 16 – ? ÷ 15 × 7 = 266

Replace the symbols according to the instructions –
72 + 19 × 13 – 16 ÷ ? × 15 + 7 = 266
72 + 247 – 16 ÷ ? × 15 + 7 = 266
319 + 7 – 16 ÷ ? × 15 = 266
326 – 266 = – 16 ÷ ? × 15
? = (16 × 15) ÷ 60
? = 4

So, 4 is the correct answer. Hence, the third option is correct.
