Question : Find the surface area of a spherical ball that has a radius of 1.1 cm.
Option 1: 16 cm2
Option 2: 12.1 cm2
Option 3: 11.2 cm2
Option 4: 15.2 cm2
Correct Answer: 15.2 cm2
Solution : Given: A spherical ball that has a radius of 1.1 cm. The surface area of the sphere of the radius $r = 4\pi r^2$ $=4\times \frac{22}{7}\times (1.1)^2$ $=4\times \frac{22}{7}\times 1.21=15.2$ cm2 Hence, the correct answer is 15.2 cm2.

Question : Comprehension: Read the given passage and answer the questions that follow. Santiniketan embodies Rabindranath Tagore's vision of a place of learning that is unfettered by religious and regional barriers. Established in 1863 with the aim of helping education go beyond the confines of the classroom, Santiniketan grew into the Visva Bharati University in 1921, attracting some of the most creative minds in the country.
He developed a curriculum that was a unique blend of art, human values, and cultural interchange. Even today, in every step, in every brick, and in every tree at Santiniketan, one can still feel his presence, his passion, his dedication, and his pride in the institution.
In 1862, Maharishi Debendranath Tagore, father of Rabindranath, was taking a boat ride through Birbhum, the westernmost corner of Bengal, when he came across a landscape that struck him as the perfect place for meditation. He bought the large tract of land built a small house and planted some saplings around it. Debendranath Tagore decided to call the place Santiniketan, or the 'abode of peace', because of the serenity it brought to his soul. In 1863, he turned it into a spiritual center where people from all religions, castes, and creeds came and participated in meditation.
In the years that followed, Debendranath's son Rabindranath went on to become one of the most formidable literary forces India has ever produced. He wrote in all literary genres but he was first and foremost a poet. As one of the earliest educators to think in terms of the global village, he envisioned an education that was deeply rooted in one's immediate surroundings but connected to the cultures of the wider world.
Located in the heart of nature, the school aimed to combine education with a sense of obligation towards the larger civic community. Blending the best of Western and traditional Eastern systems of education, the curriculum revolved organically around nature with classes being held in the open air. Tagore wanted his students to feel free despite being in the formal learning environment of a school because he himself had dropped out of school when he found himself unable to think and felt claustrophobic within the four walls of a classroom. Nature walks and excursions were a part of the curriculum, special attention was paid to natural phenomena and students were encouraged to follow the life cycles of insects, birds, and plants.
The rural paradise of Santiniketan, Tagore's erstwhile home, has become a thriving center of art, education, and internationalism over the years.

Question : If $\alpha \sin 45^{\circ}=\beta \operatorname{cosec} 30^{\circ}$, then $\frac{\alpha^4}{ \beta^4}$ is:
Option 1: $4^4$
Option 2: $3^3$
Option 3: $2^3$
Option 4: $4^3$
Correct Answer: $4^3$
Solution : $\sin 45^{\circ}$ = $\frac{1}{\sqrt2}$ $\operatorname{cosec} 30^{\circ}$ = 2 $\alpha \sin 45^{\circ}=\beta \operatorname{cosec} 30^{\circ}$ ⇒ $\alpha\times{\frac{1}{\sqrt2}}=\beta\times{2}$ ⇒ $\frac{\alpha}{\beta}$ = $2\times{\sqrt{2}}$ $\therefore$ $\frac{\alpha^4}{\beta^4}=(\frac{\alpha}{\beta})^4 = (2\times{\sqrt{2}})^4 = 64 = 4^3$ Hence, the correct answer is $4^3$.
Question : Directions: In the following question, some parts of the sentence may have some errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select 'No Error'.
He said that it was the first time (1) / that such a trick (2) / is discovered. (3) / No Error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (3)
Solution : The error lies in the third part of the sentence.
The verb "is" should be replaced with "was" in order to make the sentence obey the past tense rule. Since the reporting verb "said" is in the past tense, the verbs in the reported speech
Question : The marked price of an article is INR 10,927. Due to the festive season, a certain percentage of discount is declared. Raju buys an article at a reduced price and sells it at INR 10927, and makes a profit of 11.5%. What was the percentage discount offered?
Option 1: 10.3%
Option 2: 11.3%
Option 3: 11.5%
Option 4: 10.9%
Correct Answer: 10.3%
Solution : The marked price of the article = 10927 The selling price of the article for Raju = 10927 Profit percentage = 11.5% We know that, Cost price = $\frac{\text {Selling price}}{1 + \frac{\text{Profit}}{100}}$ = $\frac{10927\times100}{111.5}=9800$ Required discount = $\frac{\text{Marked price – Cost price}}{\text{Mark price}} \times
Question : The vitamin that is most readily manufactured in our body is:
Option 1: Vitamin A
Option 2: Vitamin B
Option 3: Vitamin C
Option 4: Vitamin D
Correct Answer: Vitamin D
Solution : The correct option is Vitamin D.
Our skin produces Vitamin D when it is exposed to Ultraviolet B (UVB) sunlight. Vitamin D3 is produced specifically when UVB rays interact with a cholesterol derivative in the skin. This vitamin is then converted into its active
