Correct Answer : B

Two digits with sum 9 and product 18 are 3 and 6, since \(3 + 6 = 9\) and \(3 \times 6 = 18\). They can be arranged as 36 or 63, and the larger is 63. Treating the digits as roots of \(x^2 - 9x + 18 = 0\) finds them directly.

Correct Answer : C

\[ \text{PW} = 3520 - 320 = \text{Rs. } 3200 \]

True discount is simple interest on the present worth:

\[ 320 = \frac{3200 \times 18 \times T}{100} = 576\,T \]

\[ T = \frac{320}{576} = \frac{5}{9} \text{ year} \]

That is about 6 months and 20 days. Using the Rs. 3520 face value in place of the present worth gives \( \tfrac{320}{633.6} = \tfrac{4}{9} \) - exactly the distractor offered.

Correct Answer : C

The year being crossed here contains a 29 February, so the shift is two days rather than one.

From 8 February 2004 to 8 February 2005 the span includes 29 February 2004, making it 366 days:

\[ 366 \equiv 2 \pmod 7 \]

Stepping back from the given Tuesday:

\[ \text{Tuesday} - 2 = \textbf{Sunday} \]

Subtracting only one day, the reflex from ordinary years, gives Monday - the trap this question is built around.

Correct Answer : A

First,we count the number of odd days for the left over days in the given period.

Here,given period is 15.8.2012 to 11.6.2013

Aug Sept Oct Nov Dec Jan Feb Mar Apr May Jun

16   30   31  30   31   31   28  31   30   31   11(left days)

2 + 2 + 3 + 2 + 3 + 3 + 0 + 3 + 2 + 3 + 4 (odd days) = 6 odd days

So,given day Thursday + 6 = Wednesday is the required result.

Correct Answer : C

\[ A = P\left(1 + \frac{R}{100}\right)^{n}, \qquad \text{CI} = A - P, \qquad \text{SI} = \frac{PRn}{100} \]

The rates differ by year, so multiply the two factors rather than raising one to a power.

\[ A = 5000 \times 1.04 \times 1.05 \]

\[ = 5000 \times 1.092 = \text{Rs. } 5460 \]

The question asks for the amount, so the Rs. 460 of interest is only an intermediate value - and it is offered as the first distractor.

Correct Answer : D

The correct pair is I R.

When the 1st letter is paired with the 26th, the 2nd with the 25th and so on, the positions in every pair add up to 27. I is the 9th letter and R the 18th, and \(9 + 18 = 27\), so I pairs with R.

The other pairs fail the test: H (8) and T (20) add to 28, J (10) and P (16) to 26, and F (6) and V (22) to 28. H actually pairs with S, J with Q, and F with U.

Correct Answer : C

Correct answer: 648

The terms are multiplied rather than added to. Dividing each by its predecessor gives the same result throughout: 24 over 8 is 3, and 72 over 24 is 3, so the ratio is 3. Multiplying the last term, 216 times 3 is 648. As a check, dividing the answer by 3 returns 216, which is the last term shown. A rule expressed in the position number can always be checked by substituting the position of a term already shown.

Correct Answer : C

The key gives Kudgarya (C).

I could not confirm this. Searches found no source naming the sutradhar (stage manager and narrator) of the Gammat folk theatre, and nothing that favours Ghughermal, Thothaya or Khamras instead, so the key is kept as printed.

In the Indian folk theatres, the sutradhar is the figure who opens the play, links the scenes and comments on them, and each form has its own local name for him; the question asks for that local name.

Operation Vijay in 1961 integrated Goa.

In December 1961 the Indian armed forces carried out Operation Vijay to end Portuguese rule in Goa, Daman and Diu. The Portuguese governor surrendered on 19 December 1961, which is still observed as Goa Liberation Day.

Hyderabad was integrated in 1948 by Operation Polo, and Junagadh in 1947-48 after a plebiscite. Jodhpur acceded by agreement in 1947. (The name Operation Vijay was used again in 1999 for the Kargil war.)

A ball pen works on capillarity and surface tension.

Ink is drawn along the narrow tube by capillary action and held at the tip by surface tension, so it does not run out. Rolling the ball picks up a film of ink and lays it on the paper.

The India–Pakistan match at Jaipur on 2 October 1983 introduced the rule that no-balls and wides are debited to the bowler's analysis.

Before this the extras were charged to the team but not to the bowler who conceded them, so his figures flattered him.

G.R. Viswanath was famous for the late cut.

The stroke plays the ball late, guiding it behind point with the face of an angled bat, and demands unusually fine timing. Viswanath scored a century in each of the Tests India won or drew after he made one - India never lost such a match.

Correct Answer : B

Correct answer: Oxygen

Oxygen makes up about 46 per cent of the crust by mass, more than every other element combined. Silicon follows at about 28 per cent, then aluminium at 8 and iron at 5. The result is surprising only if oxygen is thought of as a gas. In the crust it is locked into silicate minerals, whose building block is the \( \mathrm{SiO_4} \) tetrahedron - one silicon atom surrounded by four oxygens. Since silicates make up over 90 per cent of the crust, oxygen dominates by sheer arithmetic. The picture changes with depth. The Earth as a whole is mostly iron, because the core is iron and nickel; iron is the single most abundant element in the planet by mass. And it changes again on the largest scale: the universe is overwhelmingly hydrogen and helium, neither of which is abundant in the crust at all.
