Correct Answer : A

The clerk gave the information at 9:15 am.

Buses leave every 30 minutes, so the bus before the 9:35 one left at 9:05. The clerk said that bus had left ten minutes earlier:

\[ 9{:}05 + 10 \text{ min} = 9{:}15 \]

9:05 is the departure time of the previous bus, not the time of speaking, and 9:20 and 9:08 do not fit both facts.

Correct Answer : A

Expand the square of the sum.

\[ (a+b)^{2} = a^{2} + b^{2} + 2ab \]

\[ 22^{2} = 404 + 2ab \quad\Longrightarrow\quad 484 - 404 = 2ab \]

\[ ab = 40 \]

The two numbers turn out to be 2 and 20.

Correct Answer : A

Convert the mixed numbers to decimals and divide the areas.

\[ \text{stone} = 2.5 \times 2 = 5 \text{ m}^{2} \]

\[ \text{courtyard} = 30 \times 16.5 = 495 \text{ m}^{2} \]

\[ n = \frac{495}{5} = 99 \]

The division is exact, so the stones tile the courtyard with no cutting - which is what makes the volume comparison legitimate here.

Correct Answer : C

T is a female teacher with blue dress.
T married a lawyer. Now, P is an engineer and Q is a doctor. Clearly, T married R.
R is, thus, a male lawyer with brown dress.
One couple is RT. So, the other couple is PQ
P is a male engineer and has the same dress as R i.e., brown
Q is a female doctor and has the same dress as T i.e., blue.
S is the sister of P. S is a female engineer. Now, U remains. Since there are two lawyers, so U is a lawyer.
Both S and U have either black or green dress.

U's dress is black or green in colour

Correct answer: Chaos

The relation is word : its synonym. A command is an order; confusion is chaos. Clarity and discipline are its opposites, and a problem is something confusion may cause.

Correct Answer : A

Correct answer: 42

The gaps are 4, 6, 8, 10, which follow no constant pattern, so the rule lies in the terms rather than in the steps between them. Each term is the square of its position plus the position itself: position 2 gives 2 and position 6 gives 30. The next position is 7, which gives 42. As a check, the same rule applied to the earlier positions reproduces 2, 6, 12, 20, 30 exactly, so it accounts for every term shown and not merely the last. A square series grows faster than any arithmetic one but more slowly than a geometric one, which places it at a glance.

Correct Answer : A

Correct answer: R

The gaps widen by one each time: C to D is +1, D to F is +2, F to I is +3, I to M is +4. The next gap is +5, so from M(13) the series reaches position 18, which is R. The pattern is the same as several others of this family but started from a different letter, so the answer cannot be recalled - it has to be counted. Q at 17 results from repeating the previous gap rather than extending it.

Correct answer: 7

The code swaps the symbols: \( + \to \times \), \( - \to + \), \( \times \to \div \), \( \div \to - \). So \( 642 \times 6 \div 25 + 4 \) is read as \( 642 \div 6 - 25 \times 4 \).

Applying BODMAS to the decoded expression: \[ 642 \div 6 - 25 \times 4 = 107 - 100 = \mathbf{7} \]

Correct answer: Competitor

The question asks what is always present, not what usually is. A race is a contest, so there must be a competitor to race against. A judge, spectators and a prize are all common but dispensable.

Correct Answer : D

The oxoacid of chlorine with more oxygen atoms is stronger, so HClO3 has the highest dissociation constant, option D.

Among HClO, HBrO and HIO, the acidity falls as the halogen gets larger, and all of them are far weaker than HClO3.

For oxoacids of the same element, acidity increases with the number of oxygen atoms and the oxidation state of the central atom, so chloric acid is much stronger than hypochlorous acid. Among the hypohalous acids, acidity falls from HClO to HBrO and HIO, because the halogen gets less electronegative.

It is known as Choonp.

Choonp (chunp) is the traditional practice in Rajasthan of fixing a small gold nail or stud between the teeth, as an ornament of the teeth.

The other names are ornaments worn elsewhere on the body: the borla is a round ornament worn on the forehead at the parting of the hair, and the hamel is a necklace. Damna is not the name of this tooth ornament.

The 'Kamdhenu of Rajasthan' is the Rathi breed.

The Rathi cow comes from the arid north-west of Rajasthan, in Bikaner, Sri Ganganagar and Hanumangarh. It is known for giving a good yield of milk under harsh desert conditions on poor fodder, which earned it the name Kamdhenu of Rajasthan.

Kankrej is a dual-purpose breed of the south-west (Barmer, Jalore, Sirohi) valued for draught as well as milk, Sanchori is associated with the same region, and Jersey is an exotic breed from the Channel Islands.

All of the above are necessary.

Food security has three components: availability, meaning enough food is produced and stored; accessibility, meaning it can physically reach people; and affordability, meaning they have the money to buy it. A shortfall in any one leaves people hungry even when the other two are met.

A member of a State Public Service Commission may be removed for misbehaviour only after an enquiry by the Supreme Court of India.

The president then acts on that report. Tying removal to a Supreme Court finding rather than to the state government's will is what secures the commission's independence.
