Correct Answer : C

The probability is \(\frac{7}{18}\).

There are 36 equally likely ordered pairs (first, second). Count the pairs where the second number is a multiple of the first:

• first 1: 1, 2, 3, 4, 5, 6 (6 pairs)
• first 2: 2, 4, 6 (3 pairs)
• first 3: 3, 6 (2 pairs)
• first 4, 5 or 6: only itself (1 pair each, 3 in all)

\[ P = \frac{6+3+2+3}{36} = \frac{14}{36} = \frac{7}{18} \]

1/6 counts only the six pairs where both rolls match, and 5/18 also undercounts; 5/6 is far too large, since a large first roll such as 4, 5 or 6 allows only one second roll.

Correct Answer : B

Using BODMAS, we perform division and multiplication from left to right, then addition and subtraction.

Step 1: \(36 \div 2 = 18\)

Step 2: \(18 \times 3 = 54\)

Step 3: \(54 + 4 = 58\)

Step 4: \(58 - 6 = 52\)

Correct Answer : C

One day's work: (A+B)=1/8, (B+C)=1/12, (A+B+C)=1/6. A's work = (A+B+C) - (B+C) = 1/6 - 1/12 = 1/12. C's work = (A+B+C) - (A+B) = 1/6 - 1/8 = (4-3)/24 = 1/24. (A+C)'s one day work = 1/12 + 1/24 = (2+1)/24 = 3/24 = 1/8. So, A and C can do the work in 8 days.

Correct Answer : B

Count forward until the accumulated odd days come back to zero.

\[ 2003:1,\ 2004:2,\ 2005:1,\ 2006:1,\ 2007:1,\ 2008:2,\ 2009:1,\ 2010:1,\ 2011:1,\ 2012:2,\ 2013:1 \]

\[ \text{total} = 14 = 2 \times 7 \quad\Longrightarrow\quad 0 \text{ odd days} \]

So the calendar of 2003 repeats in 2014. Leap years contribute two odd days each, which is why the cycle is 11 years and not 7.

Correct Answer : B

The woman is Ramesh's Daughter.

The only son of Ramesh's mother is Ramesh himself (Ramesh being a man's name), so 'the daughter of the only son of my mother' is the daughter of Ramesh.

She would be his sister only if she were his mother's daughter, his niece if she were a sibling's daughter, and his cousin if she were the child of his parent's sibling. The phrase 'only son' rules all of those out.

The synonym of brusque is impolite.

Brusque describes a manner that is abrupt and offhand, short to the point of rudeness: a brusque reply. Impolite is the closest of the four.

Polite and courteous are opposites. Great has no connection with manner of speaking.

Correct Answer : D

The words are blow, scene.

The first blank follows 'began to', which takes the base form of the verb: 'the wind began to blow strongly'. The second blank is a thing the sailors admired on the horizon at sunset: a golden scene, meaning a view.

Blew is the past tense and cannot follow 'to'. Blue is a colour, not a verb. Seen is the past participle of 'see' and cannot be the object of 'admire'. Only one option has both the base-form verb and the noun meaning a view.

Twenty-four bits is three bytes per pixel:

\[ 1024\times 768\times 3 = 2{,}359{,}296\ \text{bytes} \approx 2.25\ \text{MB} \]

More than 2 MB is needed, and cards are supplied in powers of two, so 4 MB is the size required.

The headquarters of North Eastern Railway is at Gorakhpur.

Despite its name, the North Eastern Railway zone serves eastern Uttar Pradesh and parts of Uttarakhand and Bihar, and its headquarters are at Gorakhpur in Uttar Pradesh.

The zone that serves the north-eastern states is the Northeast Frontier Railway, headquartered at Maligaon in Guwahati, which is the trap. Shimla and Imphal are not zonal headquarters.

The correct matching is a-4, b-3, c-2, d-1.

Keenan Stadium is the Tata Steel cricket ground at Jamshedpur (a-4). The MECON Stadium is in Ranchi, at the MECON township in Doranda (b-3). The Paramveer Albert Ekka Stadium is named after the Param Vir Chakra awardee from Gumla district and stands in Gumla (c-2), which leaves the Indoor Stadium for Dumka (d-1).

Once Keenan Stadium is placed in Jamshedpur and the MECON Stadium in Ranchi, only one option remains: the others put Keenan Stadium in Dumka or Ranchi.
