Question 1

With which country India did its seventh edition of bilateral EKUVERIN Exercise 2016 at Kadhdhoo?

Accepted Answer

Exercise EKUVERIN is a joint military exercise conducted between India and the Maldives. The 7th edition was held in 2016 at Kadhdhoo, Maldives, focusing on counter-terrorism operations.

Question 2

P is a point outside the circle at distance of 6.5 cm from centre O of the circle. PR be a secant such that it intersects the circle at Q and R. If PQ = 4.5 cm and QR = 3.5 cm, then what is the radius (in cm) of the circle?

Accepted Answer

Using the secant property: PQ × PR = OP² - r². Here, PR = 4.5 + 3.5 = 8. So, 4.5 × 8 = 6.5² - r², which gives 36 = 42.25 - r². Thus, r² = 6.25, meaning r = 2.5 cm.

Question 3

What is the area (in sq cm) of a regular hexagon of side 9 cm?

Accepted Answer

The area of a regular hexagon is calculated using the formula (3√3/2) × a², where 'a' is the side length. For a = 9, Area = (3√3/2) × 81 = 243√3/2.

Question 4

Select the related word from the given alternatives. Tongue : Taste :: Nose : ?

Accepted Answer

The tongue is the primary sensory organ used for tasting. Similarly, the nose is the sensory organ used for the function of smelling.

Question 5

What is the average of all numbers between 11 and 80 which are divisible by 6?

Accepted Answer

The numbers form an arithmetic progression from 12 to 78. The average of an AP is (first term + last term)/2. So, (12 + 78)/2 = 90/2 = 45.

Question 6

The method of soil conservation in the coastal and dry regions where rows of trees are planted to check the wind movement to protect soil cover is called?

Accepted Answer

Shelter belts involve planting rows of trees to block wind, significantly reducing wind erosion in coastal and dry areas. This effectively protects the valuable topsoil from being blown away.

Question 7

_____________ means cases that can be directly considered by the Supreme Court without going to the lower courts before that.

Accepted Answer

Original Jurisdiction (Article 131) allows the Supreme Court to hear disputes directly, such as those between the Centre and States, without them being heard in lower courts first.

Question 8

In a majority of flowering plants, out of the four megaspores, what is the ratio of functional and degenerate megaspores?

Accepted Answer

In most angiosperms, megasporogenesis produces four megaspores. Three of them degenerate, leaving only one functional megaspore to develop into the female gametophyte. Thus, the ratio is 1:3.

Question 9

If x3 – y3 = 81 and x – y = 3, then what is the value of x2 + y2?

Accepted Answer

Use x³ - y³ = (x - y)(x² + xy + y²) to get x² + xy + y² = 27. Since (x - y)² = 9, we find xy = 6. Thus, x² + y² = 27 - 6 = 21.

Question 10

Which base is present in soap?

Accepted Answer

Soap is made via saponification, where fats or oils react with a strong base like sodium hydroxide (NaOH) or potassium hydroxide (KOH) to form soap salts.

Question 11

Which of the following has the supreme command of the Indian Defence Forces?

Accepted Answer

According to Article 53(2) of the Indian Constitution, the supreme command of the Defence Forces of the Union is vested in the President of India.

Question 12

Select the related number from the given alternatives. 39 : 52 :: 51 : ?

Accepted Answer

The numbers follow a 3:4 ratio. 39 is 13 × 3 and 52 is 13 × 4. Similarly, 51 is 17 × 3, so the next number must be 17 × 4 = 68.

Question 13

Three boxes of capacity 24 kg, 36 kg and 84 kg are completely filled with three varieties of wheat A, B and C respectively. All the three boxes were emptied and the three types of wheat were thoroughly mixed and the mixture was put back in the three boxes. How many kg of type A wheat would be there in the third box (in kg)?

Accepted Answer

The total mixture is 144 kg, with type A being 24 kg. The fraction of A in the mixture is 24/144 = 1/6. The third box holds 84 kg, so it contains (1/6) * 84 = 14 kg of type A.

Question 14

Red data book contains data of which of the following?

Accepted Answer

The Red Data Book, maintained by the IUCN, is a comprehensive document that records and details all endangered and rare species of plants, animals, and fungi globally.

Question 15

A man travelled a distance of 60 km in 7 hours. He travelled partly on foot @ 6 km/hr and partly on bicycle @ 12 km/hr. What is the distance (in kms) travelled on foot?

Accepted Answer

Let time on foot be t hours. Then 6t + 12(7 - t) = 60. Solving gives 6t = 24, so t = 4 hours. Distance on foot = 6 × 4 = 24 km.

Question 16

India is the ______ largest country in the world.

Accepted Answer

India is the 7th largest country in the world by total area, covering approximately 3.28 million square kilometers. Russia is the largest.

Question 17

Biological names are generally derived from which language?

Accepted Answer

Biological scientific names (binomial nomenclature) are primarily derived from Latin because it is a dead language, ensuring names remain universally standard and unchanged over time.

Question 19

Improve the bracketed part of the sentence. My brother is indifferent (about) whatever I say.

Accepted Answer

The adjective 'indifferent' is always followed by the preposition 'to'. It means having no particular interest or sympathy. Therefore, 'indifferent to' is the correct usage.
