Correct Answer : C

Clear the decimals by scaling both numbers by the same power of ten.

\[ \frac{0.000064}{0.016} = \frac{64}{16000} \]

\[ = 0.004 \]

The numerator has six decimal places and the denominator three, so the quotient has three.

Correct Answer : D

In stock problems, a "\( r\% \) stock at \( m \)" means Rs. 100 of face value costs Rs. \( m \) and pays Rs. \( r \) a year, so the yield on money invested is \( \tfrac{r}{m} \).

\[ \frac{12}{m} = 10\% \quad\Longrightarrow\quad m = \frac{12}{0.10} = \text{Rs. } 120 \]

A yield below the dividend rate means the stock trades above par - which rules out the Rs. 83.33 option at once.

Correct Answer : A

Using factorization method,
\(18 = 2 \times 3^2\)
\(288 = 2^5 \times 3^2\)
\(360 = 2^3 \times 3^2 \times 5\)
So H.C.F. will be minimum term present in all three,
i.e. \(2 \times 3^2 = 18\)

Correct Answer : D

Correct answer: K

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

Place K; F sits two to K’s left and M two to K’s right. H, the Scientist, must be beside K, and E four seats from H - and of the two ways of doing that, only one lets the Engineer sit two seats from E without being G or J, who must be neighbours. The Columnist then sits on the Engineer’s right, the Lawyer two to the Columnist’s right, the Financial Analyst on F’s left, the Professor beside the Engineer, and the Chartered Accountant two seats from G.

Clockwise the table reads K (Professor) → H (Scientist) → F (Doctor) → G (Financial Analyst) → J (Lawyer) → E (Chartered Accountant) → M (Columnist) → L (Engineer).

The Professor must sit beside the Engineer, L. Of L’s two neighbours one is the Columnist M, so the Professor is K.

Correct Answer : B

Correct answer: Third to the right

Only two people sit to S’s right, so S is sixth in the line, and T three places to her left is third. One person separates T from X and X sits immediately right of W, which puts X fifth and W fourth; Z, one person from W, takes the second place. U three places from X, and Y barred from either end, then leave V at the first place and U at the eighth. From left to right the line reads V, Z, T, W, X, S, Y, U.

Z sits second and X fifth. Z faces north, so her right is east, and X is three places that way.

Correct answer: All are implicit

The advertisement rests on all three: that people do give gifts to those they love, that an advertisement of this kind can sway them, and that chocolate counts as a gift at all. Remove any one and the appeal falls apart. All are implicit.

Correct Answer : B

Correct answer: 346

The series rises by 7 each time from 10, so every term leaves a remainder of 3 when divided by 7. Of the numbers offered, only 346 does: \( 346 = 7 \times 49 + 3 \). The others leave remainders of 6, 0 and 2.

Correct Answer : C

Correct answer: 180

The steps run 8, 6, 36, 6, which grow and then fall back, so a single operation cannot account for them. Two operations are applied in turn, and continuing the alternation from 60 gives 180. As a check, the step from 60 to the answer is 120, which breaks the run of preceding gaps exactly as an alternating rule demands. The distractor formed by applying the wrong operation is always among the options in questions of this shape.

Correct Answer : C

Correct answer: G

Each term is four places back from the one before: W(23), S(19), O(15), K(11). Four below 11 is position 7, which is G. Because the step is large and backwards, converting to positions is far safer than counting letters on the fingers. H at 8 is a three-step and F at 6 a five-step, the two neighbouring errors. Read in reverse the series is G, K, O, S, W, a four-step climb, which is the quickest way to confirm the answer once it has been found.

Correct Answer : C

Correct answer: North-East

Facing south, a right turn is to the west. Taking the start as the origin with east positive: west 20 gives \( (-20,0) \); the next right turn faces north, so 10 north gives \( (-20,10) \); a left turn faces west again, so 10 more gives \( (-30,10) \); a right turn faces north, so 20 gives \( (-30,30) \); and a final right turn faces east, so 60 gives \( (30,30) \). Both coordinates are positive, so he is north-east of the start.

Correct Answer : C

Correct answer: A circular shape

The question asks what is always present, not what usually is. A wheel is by definition a circular object that turns about its centre, so its shape is what makes it one. Spokes are a refinement: the earliest wheels were solid discs, and many still are - a potter’s wheel, a grindstone. Rubber is a tyre material of the last century and a half; wheels were wood and iron for millennia. An axle is the shaft a wheel turns on, so it is a separate part rather than a component of the wheel - and a wheel lying detached is still a wheel.

Correct Answer : A

The builder was Maharaja Krishnakishore Manikya.

In 1849 Maharaja Krishna Kishore Manikya moved the royal capital from Old Agartala (Old Haveli) to the present site on the banks of the Haora river, and modern Agartala was laid out at his initiative. Frequent Kuki raids and easier contact with British Bengal were the reasons given for the move.

The other three were later rulers: Bir Chandra Manikya reigned from 1862, Radha Kishore Manikya built the Ujjayanta Palace in the new capital around 1901, and Bir Bikram Kishore Manikya was the last ruling king, who died in 1947. They developed the city but did not found it.

The Twelfth Schedule, added by the 74th Amendment, lists 18 functions of municipalities. The Eighth Schedule lists the official languages and the Tenth contains the anti-defection law.

Acetic acid is the oldest known organic compound.

Vinegar, a dilute solution of it, has been made by fermenting wine since antiquity, and Jabir ibn Hayyan concentrated it by distillation in the eighth century. Urea is significant for a different reason - Wöhler's 1828 synthesis of it was the first laboratory preparation of an organic compound from inorganic material.

Radio waves are reflected by the ionosphere.

Solar ultraviolet ionises the upper atmosphere above about 60 km, and the free electrons reflect radio waves back to earth, allowing transmission far beyond the horizon. Reflection is strongest at night, when the lower absorbing layers thin out - which is why distant stations come in after dark.

K.D. Jadhav won bronze in freestyle wrestling at the 1952 Helsinki Olympics, the first individual Olympic medal won by an Indian.

India's earlier medals had all been won by the hockey team. Jadhav's achievement went largely unrewarded in his lifetime; he was given the Arjuna Award only posthumously, in 2001.
