Correct Answer : D

The series is the cubes of the natural numbers.

\[ 1^{3},\; 2^{3},\; 3^{3},\; 4^{3},\; 5^{3},\; 6^{3},\; 7^{3} = 1,\; 8,\; 27,\; 64,\; 125,\; 216,\; 343 \]

The fifth term should be \( 5^{3} = 125 \), not 124.

So 124 is wrong - off by exactly one, which is what makes it hard to spot.

Correct Answer : B

\[ \text{Amount} = \text{PW}\left(1 + \frac{RT}{100}\right), \qquad \text{TD} = \text{Amount} - \text{PW} \]

With \( T = 2\tfrac{1}{2} = 2.5 \) years at 15%:

\[ \frac{RT}{100} = \frac{15 \times 2.5}{100} = 0.375 \]

\[ \text{PW} = \frac{2310}{1.375} = \text{Rs. } 1680 \]

Checking: the discount is \( 2310 - 1680 = 630 \), and 37.5% of 1680 is 630 - interest on the present worth, exactly as the definition requires.

Correct Answer : A

The year 2004 is a leap year. So, it has 2 odd days.

But, Feb 2004 not included because we are calculating from March 2004 to March 2005. So it has 1 odd day only.

The day on 5th March, 2005 will be 1 day beyond the day on 5th March, 2004.

Given that, 5th March, 2005 is Monday.

5th March, 2004 is Sunday (1 day before to 5th March, 2005).

Correct answer: A

All eight face the centre, so each person’s left is the next seat clockwise and their right the next seat anticlockwise.

Place the Managing Director; A sits three to his right, and H three the other way, since only two people separate them. The Manager, two seats to E’s left, must have the Group Leader and the Financial Advisor on either side - and of the three seats that allows, only one leaves room for B three seats to the Financial Advisor’s left. That fixes H as the Manager and E beside the Managing Director. The Vice President may sit next to neither the Managing Director nor A or H, which leaves a single seat, and the Company Secretary must be beside him. A is not the Chairman, so A is President and E the Chairman - and C then takes the seat on the Chairman’s right, with F kept clear of A and G clear of the Manager.

Clockwise the table reads C (Managing Director) → E (Chairman) → F (Group Leader) → H (Manager) → D (Financial Advisor) → A (President) → G (Vice President) → B (Company Secretary).

A cannot be Vice President, Company Secretary or Chairman, and the other posts are taken by the time his seat is reached, so A is the President.

The statement asserts that the structure was originally a 'brilliant' one. So, there is no need of a new architectural design, as mentioned in I. Also, it is given that paucity of funds is responsible for the dilapidated condition of the structure. Thus, only III follows while II doesn't.

Correct Answer : D

Writing the first half of the alphabet in reverse order and leaving the second half unchanged gives the series: M L K J I H G F E D C B A N O P Q R S T U V W X Y Z. In this series, counting from the end, the 7th letter is T (Z, Y, X, W, V, U, T).

T is at position 20 from the left. The 11th letter to its left is at position 20 - 11 = 9, and the 9th letter of the new series is E. So the answer is E. The letters R, F and I are the letters at other positions in the series, which come from miscounting the 7th letter from the end or the 11 places.

Correct Answer : B

The missing number is 182.

Each term is the product of two consecutive numbers:

\[ \begin{aligned} 132 &= 11 \times 12 \\ 156 &= 12 \times 13 \\ ? &= 13 \times 14 = 182 \\ 210 &= 14 \times 15 \end{aligned} \]

The pattern continues with \(240 = 15 \times 16\) and \(272 = 16 \times 17\). The differences 24, 26, 28, 30, 32 confirm it.

Correct Answer : A

The chain reaction is controlled with cadmium rods.

Cadmium and boron have very large neutron-absorption cross-sections, so pushing the rods further into the core soaks up surplus neutrons and slows the reaction; withdrawing them speeds it up. Graphite is a moderator, not an absorber - it slows neutrons rather than removing them.

The bomb strikes the ground 3.33 km from A.

Vertically it starts with no downward velocity: \[t = \sqrt{\frac{2h}{g}} = \sqrt{\frac{2\times1960}{9.8}} = 20\ \mathrm{s}\]

Horizontally it keeps the aircraft's speed of \(166.7\ \mathrm{m\,s^{-1}}\): \[x = 166.7\times20 \approx 3.33\ \mathrm{km}\]

Prorogation ends a session but not the House; dissolution ends the House itself. Adjournment, by contrast, is done by the Speaker and merely suspends a sitting.

The key gives the Scheduled Caste and Tribe Welfare Department.

The Dr. Bhimrao Ambedkar Medhavi Vidyarthi scheme gives one-time cash awards to Scheduled Caste students of the state who stand first, second or third in the Class 10 and 12 board examinations. A scheme-information site describes it as run by the state's Scheduled Caste Welfare Department since 2007, so the welfare department for Scheduled Castes is the one to pick, and option A is the only option naming it (its wording adds 'and Tribe').

The Higher Education and School Education departments run other schemes, and the Tribal Affairs Department deals with Scheduled Tribes, not this award. I did not find an official government page naming the department, so the confirmation is from a secondary source.
