Question 2

Through photosynthesis at least a half of the total carbon dioxide fixation on earth is carried out by?

Accepted Answer

Algae are primarily aquatic and perform about half of all photosynthesis on Earth, fixing massive amounts of carbon dioxide into organic compounds in marine and freshwater ecosystems.

Question 3

If A/3 = B/2 = C/5, then what is the value of ratio (C + A)2 : (A + B)2 : (B + C)2?

Accepted Answer

Let A=3, B=2, and C=5. Calculate the sums: C+A = 8, A+B = 5, B+C = 7. Squaring these values gives 64, 25, and 49. The ratio is 64:25:49.

Accepted Answer

The Bharat Ratna is India's highest civilian award, followed by the Padma Vibhushan as the second highest. It is awarded for exceptional and distinguished service across all fields.

Question 5

In ΔABC, ∠BAC = 90° and AD is drawn perpendicular to BC. If BD = 7 cm and CD = 28 cm, then what is the length (in cm) of AD?

Accepted Answer

In a right-angled triangle, the altitude drawn to the hypotenuse satisfies AD² = BD × CD. Here, AD² = 7 × 28 = 196, so AD = 14 cm.

Question 6

By what least number should 1200 be multiplied so that it becomes a perfect square?

Accepted Answer

Prime factorize 1200 as 2^4 × 3^1 × 5^2. For a perfect square, all exponents must be even. Multiplying by 3 makes the exponent of 3 even (3^2).

Question 7

The weights of 4 boxes are 100, 70, 50 and 90 kilograms. Which of the following cannot be the total weight, in kilograms, of any combination of these boxes and in a combination a box can be used only once?

Accepted Answer

Calculate possible sums of the given weights (100, 70, 50, 90). The sum of all four is 310. The sum of 70, 50, and 90 is 210. The sum of 100, 70, and 90 is 260. 230 cannot be formed.

Question 8

Two numbers are 10% and 20% lesser than a third number respectively. By how much percent is the second number should be enhanced to make it equal to the first number?

Accepted Answer

Let the third number be 100. The first and second numbers become 90 and 80. To make 80 equal to 90, increase it by 10. Percentage increase = (10/80) × 100 = 12.5%.

Question 9

Bangladesh does not share its border with which Indian state?

Accepted Answer

Bangladesh shares borders with West Bengal, Assam, Meghalaya, Tripura, and Mizoram. Jharkhand is a landlocked state located further west, so it does not share an international border with Bangladesh.

Question 10

A train leaves Delhi at 10 a.m. and reaches Jaipur at 4 p.m. on same day. Another train leaves Jaipur at 12 p.m. and reaches Delhi at 5 p.m. on same day. What is the time of day (approximately) when the two trains will meet?

Accepted Answer

Let distance = 30 units (LCM of 6h and 5h). Speeds are 5 and 6. Train 1 covers 10 units by 12 p.m. Remaining 20 units covered at relative speed 11. Time = 20/11 hrs ≈ 1 hr 49 mins after 12 p.m.

Question 11

In 1528, __________ defeated the Rajputs at Chanderi.

Accepted Answer

In the Battle of Chanderi in 1528, Babur defeated the Rajput forces led by Medini Rai, further consolidating Mughal power in northern India after Panipat and Khanwa.

Question 12

Two people A and B are at a distance of 260 km from each other at 9:00 a.m. A immediately starts moving towards B at a speed of 25 km/h and at 11:00 a.m. B starts moving towards A at a speed of 10 km/hr. At what time (in p.m.) will they meet each other? ?

Accepted Answer

By 11:00 a.m., A travels 50 km (25×2). Remaining distance is 210 km. Relative speed is 35 km/h (25+10). Time taken = 210/35 = 6 hours. 11:00 a.m. + 6 hours = 5:00 p.m.

Question 13

If "x" denotes "added to", "÷" denotes "subtracted from", "+" denotes "divided by" and "–" denotes "multiplied by", then 14 x 12 – 16 ÷ 18 = ?

Accepted Answer

Substitute the signs to get 14 + 12 * 16 - 18. Using BODMAS, first multiply (12 * 16 = 192), then add 14 (206), and finally subtract 18 to get 188.

Question 14

Which of the following is an Indian military decoration awarded for valour, courageous action or self-sacrifice away from the battlefield?

Accepted Answer

The Ashok Chakra is India's highest peacetime military decoration awarded for valour, courageous action, or self-sacrifice away from the battlefield. The other options are civilian, sports, or film awards.

Question 15

∆ABC is right angled at B. BD is an altitude. AD = 4 cm and DC = 9 cm. What is the value of BD (in cm)?

Accepted Answer

In a right-angled triangle, the square of the altitude to the hypotenuse equals the product of the hypotenuse segments. BD² = AD × DC = 4 × 9 = 36. Thus, BD = 6 cm.

Question 16

Which Fundamental Right in the Indian Constitution includes equal access to shops, bathing, ghats, hotels etc?

Accepted Answer

Article 15(2) under the Right to Equality prohibits discrimination on grounds of religion, race, caste, sex, or place of birth regarding access to shops, hotels, and public bathing ghats.

Question 17

What is the sum of the first 11 terms of an arithmetic progression if the first term is -31 and last term is 29?

Accepted Answer

Use the sum formula for an AP: S = n/2 × (a + l). Here, S = 11/2 × (-31 + 29) = 11/2 × (-2) = -11.

Question 18

Which colour is formed when Blue and Green are mixed?

Accepted Answer

In the RGB color model, mixing the primary colors blue and green produces the secondary color cyan. This is a fundamental principle of additive color mixing used in screens.

Question 19

The 7th and 12th term of an arithmetic progression are -15 and 5 respectively. What is the 16th term?

Accepted Answer

Using a+6d = -15 and a+11d = 5, we get 5d = 20, so d = 4. Then a = -39. The 16th term is a+15d = -39 + 60 = 21.

Question 20

Kyoto Protocol's (an international treaty to reduce greenhouse gas emissions) first meeting was held at which country?

Accepted Answer

The Kyoto Protocol was adopted in Kyoto, Japan, on December 11, 1997. Therefore, its first major meeting and adoption took place in Japan to combat global warming.
