Question 3

How many spherical balls of radius 1 cm can be made by melting a hemisphere of radius 6 cm? ?

Accepted Answer

Volume of hemisphere = (2/3)π(6)³ = 144π. Volume of one spherical ball = (4/3)π(1)³ = (4/3)π. Number of balls = 144π / (4/3)π = 108.

Question 5

Chemical formula for sulphurous acid is:

Accepted Answer

Sulphurous acid is formed when sulfur dioxide dissolves in water. Its chemical formula is H2SO3, containing two hydrogen, one sulfur, and three oxygen atoms.

Question 6

From the given words, select the word which cannot be formed using the letters of the given word. SCALDING SCALDING

Accepted Answer

The original word 'SCALDING' does not contain the letter 'E'. Therefore, the word 'DICES' cannot be formed from its letters.

Question 7

Nereis, Pheretima (Earthworm) and Hirudinaria (blood sucking leech) are examples of which Phylum?

Accepted Answer

Nereis, earthworms, and leeches belong to the phylum Annelida. These organisms are characterized by their ring-like segmented bodies, bilateral symmetry, and a true coelom.

Question 8

A man gains 15% by selling a calculator for a certain price. If he sells it at the triple the price, then what will be the profit percentage?

Accepted Answer

Let CP = 100. Initial selling price = 115 (15% profit). New selling price = 3 × 115 = 345. New profit = 345 - 100 = 245, so the profit percentage is 245%.

Question 9

In the following question, out of the four alternatives, select the alternative which best expresses the meaning of the idiom/phrase. Go for a song

Accepted Answer

The idiom 'go for a song' means to be sold or obtained for a very low price, implying something is sold cheaply.

Question 10

Which of the following provision needs a special majority in Parliament?

Accepted Answer

Amending Fundamental Rights requires a special majority under Article 368 (2/3rd members present and voting, plus absolute majority). The other options only require a simple majority in Parliament.

Question 11

Two cyclists P and Q cycle at 20 km/hr and 16 km/hr towards each other respectively. What was the distance (in kms) between them when they started if they met after 40 minutes?

Accepted Answer

Since they move towards each other, relative speed = 20 + 16 = 36 km/hr. Time = 40 mins = 2/3 hr. Distance = Speed × Time = 36 × (2/3) = 24 km.

Question 12

A and B together do a job in 6.75 days and A could do the job in 9 days if he worked alone. How many days would B take to do the job if he worked alone?

Accepted Answer

Let total work be the LCM of 6.75 (27/4) and 9, which is 27 units. Efficiency of (A+B) = 4, A = 3. B's efficiency = 4 - 3 = 1. B's time = 27/1 = 27 days.

Question 13

If x + (1/x) = √13, then what is the value of x5 – (1/x5)?

Accepted Answer

First, find x - 1/x = √(13 - 4) = 3. Then x² + 1/x² = 11 and x³ - 1/x³ = 3³ + 3(3) = 36. Finally, x⁵ - 1/x⁵ = (36 × 11) - 3 = 393.

Question 14

In ∆ABC, AD is the median and AD = (1/2)BC. If ∠ACD = 40°, then what is the value (in degrees) of ∠DAB?

Accepted Answer

Since AD is the median, BD = DC. Given AD = BC/2, AD = DC, making ∆ADC isosceles. So ∠DAC = 40°. Exterior ∠ADB = 80°. In isosceles ∆ADB, ∠DAB = (180°-80°)/2 = 50°.

Question 15

Synapse gap is present between which of the following?

Accepted Answer

A synapse is the microscopic gap between two adjacent neurons where nerve impulses are transmitted using chemical messengers called neurotransmitters.

Question 16

Who discovered electricity and invented the lightning rod and bifocals?

Accepted Answer

Benjamin Franklin is famous for his kite experiment proving lightning is electricity. He also invented the lightning rod to protect buildings and bifocal glasses for vision correction.

Question 17

The weights of 4 boxes are 30, 70, 60 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

The possible sums of combinations are 250 (all four), 220 (70+60+90), and 190 (30+70+90). There is no combination of these weights that adds up to exactly 200.

Question 18

In the following question, select the related number from the given alternatives. 49 : 169 : : 66 : ? 49 : 169 : : 66 : ?

Accepted Answer

The logic is the square of the sum of the digits. For 49, (4+9)^2 = 13^2 = 169. Similarly, for 66, (6+6)^2 = 12^2 = 144.

Question 19

In triangle ABC, ∠ABC = 90°. BP is drawn perpendicular to AC. If ∠BAP = 50°, then what is the value (in degrees) of ∠PBC?

Accepted Answer

In right triangle ABC, ∠C = 180° - 90° - 50° = 40°. In right triangle BPC, ∠PBC = 180° - 90° - 40° = 50°. Alternatively, ∠PBC always equals ∠A.

Question 20

Who is the recipient of Arjuna Award 2016 in the field of athletics? 9/8/2017 Staff Selection Commision

Accepted Answer

Lalita Babar, an Indian long-distance runner, received the Arjuna Award in 2016 for her outstanding performance in athletics, particularly in the 3000m steeplechase.
