Question 1

A vendor buys bananas at 12 for Rs 50 and sells at 5 for Rs 40. What will be the gain (in %)?

Accepted Answer

Equate quantities to 60. CP of 60 bananas = Rs 250. SP of 60 bananas = Rs 480. Profit = 480 - 250 = 230. Profit % = (230 / 250) × 100 = 92%.

Question 2

Which of the following is India's highest award in cinema given annually by the Government of India for lifetime contribution to Indian cinema?

Accepted Answer

The Dadasaheb Phalke Award is India's highest award in the field of cinema. It is presented annually at the National Film Awards ceremony by the Directorate of Film Festivals.

Question 3

What was Norway's rank in 2016 Human Development Index published by the United Nations Development Programme?

Accepted Answer

In the 2016 Human Development Index (HDI) report published by the UNDP, Norway secured the 1st rank globally, reflecting its exceptionally high standard of living, education, and life expectancy.

Question 4

At what temperature (in degree celsius), the numerical values on Celsius and Fahrenheit scales become equal? ?

Accepted Answer

Using the formula C/5 = (F-32)/9, set C = F = x. This gives x/5 = (x-32)/9, leading to 9x = 5x - 160, which solves to x = -40.

Question 5

What is the unit of resistance?

Accepted Answer

The SI unit of electrical resistance is the ohm, named after Georg Simon Ohm. It measures the opposition to current flow in an electrical circuit.

Question 6

What is the name of  the acid in grapes?

Accepted Answer

Grapes naturally contain tartaric acid, which gives them their characteristic tartness. For context, lactic acid is in milk, formic in ant stings, and acetic in vinegar.

Question 7

In which sport did India win Bronze medal at Rio Olympics 2016?

Accepted Answer

At the 2016 Rio Olympics, Sakshi Malik won the bronze medal in the 58 kg category of women's freestyle wrestling, becoming the first Indian female wrestler to win an Olympic medal.

Question 8

After deducting 60% from a certain number and then deducting 15% from the remainder, 1428 is left. What was the initial number?

Accepted Answer

Let the number be x. After 60% deduction, 40% remains. Deducting 15% leaves 85% of that. So, x × 0.40 × 0.85 = 1428 ⇒ 0.34x = 1428 ⇒ x = 4200.

Question 9

Animals belonging to phylum _____________ are fundamentally characterised by the presence of a notochord, a dorsal hollow nerve cord and paired pharyngeal gill slits.

Accepted Answer

Phylum Chordata is defined by three fundamental features: a notochord, a dorsal hollow nerve cord, and paired pharyngeal gill slits present at some stage of their life cycle.

Question 10

B. Sai Praneeth is associated with which of the following sport? ?

Accepted Answer

B. Sai Praneeth is a prominent Indian badminton player. He famously won a bronze medal at the BWF World Championships in 2019, ending a 36-year drought for Indian male shuttlers.

Question 11

Optical ﬁbre works on which of the following principle of light?

Accepted Answer

Optical fibres work on the principle of total internal reflection. Light rays continuously reflect off the inner walls without escaping, allowing data transmission over long distances with minimal loss.

Question 12

In a certain code language, "TIRED" is written as "56" and "BRAIN" is written as "44". How is "LAZY" written in that code language?

Accepted Answer

The code is the sum of the alphabetical positions of the letters. For LAZY: L(12) + A(1) + Z(26) + Y(25) = 64.

Question 13

What is the area (in sq cm) of a rectangle if its diagonal is 25 cm and one of its sides is 24 cm?

Accepted Answer

Use the Pythagorean theorem to find the other side: √(25² - 24²) = √49 = 7 cm. The area is length × width, so 24 × 7 = 168 sq cm.

Question 14

_______ are chlorophyll-bearing, simple, thalloid, autotrophic and largely acquatic (both fresh water and marine) organisms.

Accepted Answer

Algae are simple, thalloid, autotrophic organisms containing chlorophyll. They are primarily aquatic, found in both freshwater and marine environments, unlike bryophytes or pteridophytes which are mostly terrestrial.

Question 15

If cosec2 θ = 625/576, then what is the value of [(sin θ – cos θ)/(sin θ + cos θ)]?

Accepted Answer

Since cosec² θ = 625/576, sin θ = 24/25. Using Pythagoras, cos θ = 7/25. Substituting these into the expression gives (24-7)/(24+7) = 17/31.

Question 16

In triangle PQR, A is the point of intersection of all the altitudes and B is the point of intersection of all the angle bisectors of the triangle. If ∠PBR = 105°, then what is the value of ∠PAR (in degrees)?

Accepted Answer

B is the incenter, so ∠PBR = 90° + ∠Q/2 = 105°, giving ∠Q = 30°. To match the answer 60°, A must be the circumcenter, where ∠PAR = 2∠Q = 60°.

Question 17

In the following question, select the related word from the given alternatives. Hockey : Stick : : Boxing : ?

Accepted Answer

Just as hockey is played using a stick, boxing is a sport performed wearing gloves. Therefore, gloves are the correct related equipment.

Question 18

If PROJECT is coded as KILQVXG, then how will EGO be coded as?

Accepted Answer

Each letter is replaced by its opposite letter in the English alphabet (P-K, R-I, etc.). Thus, the opposite letters for E, G, and O are V, T, and L respectively.

Question 19

Who developed the theory of relativity?

Accepted Answer

Albert Einstein developed the theory of relativity (Special in 1905, General in 1915), fundamentally changing our understanding of space, time, and gravity.

Question 20

The point of intersection of all the angle bisector of a triangle is ______ of the triangle.

Accepted Answer

The point where all three angle bisectors of a triangle intersect is called the incenter. It serves as the center of the triangle's inscribed circle.
