Correct Answer : B

The difference for school B is 750. From the data the number of students from school B who appeared is 2000 and the number who qualified is 1250. \[ 2000 - 1250 = 750 \] The values 650, 850 and 950 do not match the difference; 650 and 850 are close to it, but they are not the figures of the bars of school B.

Three-fifths taken away leaves two-fifths.

\[ x - \frac{3x}{5} = \frac{2x}{5} = 50 \]

\[ x = 125 \]

Correct Answer : C

Work in centimetres throughout: the cylinder is \( r = 100 \) cm, \( h = 500 \) cm.

\[ V_{\text{cyl}} = \pi (100)^{2}(500) = 5{,}000{,}000\pi \text{ cm}^{3} \]

\[ V_{\text{cone}} = \frac{1}{3}\pi (50)^{2}(50) = \frac{125000\pi}{3} \text{ cm}^{3} \]

\[ n = \frac{5{,}000{,}000\pi}{125000\pi/3} = \frac{5{,}000{,}000 \times 3}{125000} = 120 \]

Mixing metres and centimetres is the trap here - the units must be made consistent before any division.

Let the total profit be \(Rs. 100.\)

After paying to charity, Rupams's share \(= rs. (95 \times \frac{3}{5}) = Rs. 57.\)

If Rupam's share is \(Rs. 57,\) total profit \(= Rs. 100.\)

If Rupam's share \(Rs. 855,\) total profit \(= (\frac{100}{57} \times 855) = 1500.\)

Correct Answer : C

Correct answer: A is true but R is false.

Pluto is indeed the coldest of the bodies traditionally counted as planets, at around \( -230^{\circ}\mathrm{C} \), so A is true. But the cause is its enormous distance from the sun - sunlight there is some 1600 times fainter than at the earth - not the slant of the rays, which is what makes the earth’s poles cold. R is false.

Correct answer: Allergy

The relation is substance : the condition it causes. Aflatoxin, produced by moulds on stored grain and nuts, causes food poisoning; histamine, released by the body’s mast cells, produces the swelling, itching and sneezing of an allergy.

Correct answer: K

The series moves backwards by a growing amount: Z to Y is -1, Y to W is -2, W to T is -3, T to P is -4. The next step is -5, and five below P(16) is position 11, which is K. Growing gaps in reverse are the hardest of these to read, because the letters accelerate away from the end of the alphabet; converting to positions removes the difficulty entirely.

Correct answer: between Peter and Kenel

Chumley and Senthil take the two ends. Chumley must sit next to Peter, so Peter is in the second seat. Donald may not sit next to Senthil, so he cannot take the fourth seat and must take the third. Kenel must sit next to Donald, and the only seat left is the fourth. The order is Chumley, Peter, Donald, Kenel, Senthil.

Correct Answer : D

Correct answer: Y

The letters sit at the positions of the perfect squares: A is 1, D is 4, I is 9, P is 16, so the next is position 25, which is Y. The gaps between them grow by two each time - 3, 5, 7, then 9 - which is the same pattern seen from the other side.

The Matsya Union was formed from Alwar, Bharatpur, Dholpur, Karauli.

The Matsya Union, the first stage of the integration of Rajasthan, was inaugurated on 18 March 1948 by joining the four princely states of Alwar, Bharatpur, Dholpur and Karauli (with the Neemrana thikana). It took its name from the ancient Matsya kingdom of the same region.

Pluto was reclassified as a dwarf planet by the International Astronomical Union in 2006. It meets two of the three tests for a planet - it orbits the Sun and is round under its own gravity - but it has not cleared its orbital neighbourhood, sharing the Kuiper Belt with many similar bodies.

Mercury, Mars and Uranus remain full planets.

Correct answer: A hygrometer

A hygrometer measures the water vapour content of the air. The classic form is the wet-and-dry-bulb pair, in which one thermometer is kept damp by a wick: evaporation cools it, and the gap between the two readings gives the relative humidity from a table. The drier the air, the faster the evaporation and the wider the gap. Note the near-identical distractor. A hydrometer, spelt with a d, measures the density of a liquid by how far it floats in it - it has nothing to do with the atmosphere, and is used to test battery acid or the sugar content of a brewing wort. A barometer measures atmospheric pressure, and an anemometer measures wind speed.

The limit is ten percent of the child's weight.

The Karnataka government's order of May 2019 directed that a school bag should not weigh more than 10% of the child's body weight. This follows the widely used guideline that heavy bags carried daily strain children's backs and posture, and it applies to government, aided and unaided schools alike.

Five and eight percent are stricter than the order, and fifteen percent is more lenient than the guideline it adopts.

The crop given the GI tag was Tur dal of Kalaburagi.

Kalaburagi tur dal (pigeon pea) received a Geographical Indication tag in 2019. The district, in the Kalyana Karnataka region, is known as the 'tur bowl' of the state, and its dal is valued for its taste, quick cooking and long shelf life, which are attributed to the region's black soils.

Jowar of Bijapur, cotton of Raichur and wheat of Bidar are important crops of north Karnataka, but none of them was the crop that received the GI tag.
