Question 1

Term ' Gambit ' is associated with which of the following sport?

Accepted Answer

A 'Gambit' is a chess opening strategy where a player sacrifices material, usually a pawn, to achieve a favorable position or tactical advantage.

Question 2

In the following question, select the missing number from the given series. 1, 3, 6, 11, 18, ? 1, 3, 6, 11, 18, ?

Accepted Answer

The differences between consecutive terms are 2, 3, 5, and 7, which are consecutive prime numbers. The next prime is 11, so 18 + 11 = 29.

Question 3

In the following question, select the related number from the given alternatives. 101 : 10201 : : 107 : ? 101 : 10201 : : 107 : ?

Accepted Answer

The pattern is x : x². The square of 101 is 10201. Similarly, the square of 107 is 11449.

Question 4

The sum of a fraction and 10 times its reciprocal is 37/4. What is the fraction?

Accepted Answer

Let the fraction be x. The equation is x + 10/x = 37/4. Testing option 1 (5/4): 5/4 + 10(4/5) = 5/4 + 8 = 37/4. It satisfies the condition.

Question 5

Δ ABC is right angled at B. If m∠A = 30o, what is the length of AB (in cm), if AC = 10 cm?

Accepted Answer

In right triangle ABC, cos(30°) = Base/Hypotenuse = AB/AC. So, √3/2 = AB/10, which gives AB = 5√3 cm.

Question 6

If A : B = 2 : 5, B : C = 4 : 3 and C : D = 2 : 1, then what is value of A : C : D?

Accepted Answer

Combine A:B = 2:5 and B:C = 4:3 to get A:B:C = 8:20:15. Then combine with C:D = 2:1 to get A:B:C:D = 16:40:30:15. Thus, A:C:D = 16:30:15.

Question 7

Which play of Shakespeare's was recently claimed to be dated wrongly?

Accepted Answer

Researchers recently claimed that Shakespeare's famous tragedy "Hamlet" was written earlier than traditionally believed, challenging the established chronological order of his works.

Question 8

The total trade for Year 2 and Year 4 is same. If exports of Year 4 are 315 crore dollars, then what are the imports (in crore dollars) of Year 2? ?

Accepted Answer

Total trade equals exports plus imports. By adding Year 4's given exports to its imports from the chart, and equating it to Year 2's total trade, we find Year 2's imports as 318.5.

Question 9

In the following question, select the related word from the given alternatives. Frog : Amphibian : : Lizard : ?

Accepted Answer

Just as a frog belongs to the amphibian class of animals, a lizard belongs to the reptile class. Thus, reptile is the correct answer.

Question 10

A number is greater than 58 times its reciprocal by 3/4. What is the number?

Accepted Answer

Let the number be x. The equation is x - 58/x = 3/4. By checking the options, if x = 8, 8 - 58/8 = 8 - 29/4 = 3/4. Thus, 8 is correct.

Question 11

The salt concentration (measured as salinity in parts per thousand), is less than ______ % in inland waters.

Accepted Answer

Inland waters (freshwater bodies) typically have a salinity of less than 5 parts per thousand (ppt). In contrast, sea water is around 30-35 ppt.

Question 12

Animals in which the cells are arranged in two embryonic layers are called ________.

Accepted Answer

Animals with two embryonic layers (ectoderm and endoderm) are called diploblastic. Examples include sponges and cnidarians. Triploblastic animals have a third layer, the mesoderm.

Question 13

The collection of all possible combinations of the goods and services that can be produced from a given amount of resources and a given stock of technological knowledge is called the ____________ of the economy.

Accepted Answer

It represents the maximum potential output of an economy given its resources and technology, defining the production possibility set or frontier.

Question 14

In a row of 74 girls, Shweta is 27th from left end. Palak is 7th to the right of Shweta. What is Palak's position from the right end of the row?

Accepted Answer

Palak's position from the left = 27 + 7 = 34. Her position from the right end = Total - Left + 1 = 74 - 34 + 1 = 41.

Question 15

On the basis of distribution, resources can be classified into ____________?

Accepted Answer

Based on distribution, resources are classified as ubiquitous (found everywhere, like air) or localized (found in specific places). Actual and potential classifications are based on the level of development.

Question 16

Price of a diamond is directly proportional to square of its weight. A man broke the diamond accidently in three pieces in the ratio of 3 : 5 : 7 and thus loses Rs 42600. What was the original price (in Rs) of the diamond?

Accepted Answer

Total weight = 3+5+7 = 15. Original price ∝ 15² = 225. New price ∝ 3² + 5² + 7² = 83. Loss = 225 - 83 = 142 units. 142 units = 42600, so 1 unit = 300. Original price = 225 × 300 = 67500.

Question 17

What is the value of the Least Distance of Distinct vision (in cm) for a normal human being?

Accepted Answer

For a normal human eye, the least distance of distinct vision is 25 cm. Objects closer than this appear blurred because the eye lens cannot accommodate further.

Question 18

19th SAARC Summit was planned to be held in November 2016 but it got postponed. Which country was its host?

Accepted Answer

The 19th SAARC Summit was scheduled to be held in Islamabad, Pakistan in November 2016. It was cancelled after India and other nations boycotted it following the Uri terror attack.

Question 19

PQRS is a cyclic quadrilateral and PQ is the diameter of the circle. If ∠RPQ = 38°, then what is the value (in degrees) of ∠PSR? ?

Accepted Answer

Since PQ is the diameter, ∠PRQ = 90°. In ∆PRQ, ∠PQR = 180° - (90° + 38°) = 52°. For cyclic quadrilateral PQRS, opposite angles sum to 180°, so ∠PSR = 180° - 52° = 128°.

Question 20

ΔXYZ is similar to ΔPQR. If ratio of Perimeter of ΔXYZ and Perimeter of ΔPQR is 16:9 and PQ = 3.6 cm, then what is the length(in cm) of XY?

Accepted Answer

For similar triangles, the ratio of perimeters equals the ratio of corresponding sides. So, XY/PQ = 16/9. Substituting PQ = 3.6 gives XY = (16/9) × 3.6 = 6.4 cm.
