Statement: In spite of less than normal rainfall in the catchment areas during the first two months of monsoon of the lakes supplying water to the city the authority has not yet affected any cut in the water supply to the city.
Assumptions:
1. The rainfall during the remaining part of the monsoon may be adequate for normal water supply.
2. The present water level of the lakes supplying water to the city may be adequate for normal supply.

Quantitative Aptitude [ Question No: 1 To 1 ] :
Two dice are tossed simultaneously. Find the probability that the total is a prime number.
Your Answer : (Not Answered)
Correct Answer : B
Two dice give 36 outcomes. The prime totals are 2, 3, 5, 7 and 11.
- sum 2: 1 way
- sum 3: 2 ways
- sum 5: 4 ways
- sum 7: 6 ways
- sum 11: 2 ways
\[ 1 + 2 + 4 + 6 + 2 = 15 \quad\Longrightarrow\quad P = \frac{15}{36} = \frac{5}{12} \]
9 is not prime (\( 3 \times 3 \)) and neither is 1, which is where miscounts usually creep in.

Assumptions:
1. The rainfall during the remaining part of the monsoon may be adequate for normal water supply.
2. The present water level of the lakes supplying water to the city may be adequate for normal supply.
Your Answer : (Not Answered)
Correct Answer : E
The statement clearly indicates that at present the water level of the lakes is adequate. There is nothing of a shortage to induce a cut in water supply and still there is time to wait and watch the performance of rains during the remaining monsoon period. So, both I and II are implicit.
A printer numbers the pages of a book starting with 1A. If 4S is the last page of the book, then how many pages are in the book ?
Your Answer : (Not Answered)
Correct Answer : C
The book has 97 pages.
The pages are labelled with a number followed by a letter: 1A, 1B, ... 1Z, then 2A to 2Z, then 3A to 3Z, then 4A onward. Each number therefore covers 26 pages, one for each letter.
\[ \begin{aligned} 1A \text{ to } 3Z &= 3 \times 26 = 78 \\ 4A \text{ to } 4S &= 19\ (\text{S is the 19th letter}) \\ \text{total} &= 78 + 19 = 97 \end{aligned} \]
104 would be four full sets of 26 (up to 4Z), and 98 and 95 miscount the letters of the last set.
What does 'nip' stand for in a code language ?
Statements:
1. In the code language, 'that is very beautiful' is written as 'se nip sre num'
2. In the same code language, 'my house is beautiful' is written as 'nip sto sre tip'.
Your Answer : (Not Answered)
Correct Answer : D
In 1 and 2, the common codes are 'nip' and 'sre' and the common words are 'is' and 'beautiful' So, 'nip' and 'sre' are the codes for 'is' and 'beautiful'. But, the exact word for 'nip' cannot be found out.

Correct Answer : D
Correct answer: 124950
Each term is a cube times a thousand, less ten times its root: \( 1000-10 \), \( 8000-20 \), \( 27000-30 \), \( 64000-40 \), so the next is \( 125000 - 50 = \mathbf{124950} \).

Your Answer : (Not Answered)
Correct Answer : C
One rutherford is a unit of radioactivity equal to 106 disintegrations per second, so option C is correct.
The becquerel (1 disintegration per second) and the curie (3.7 x 1010 per second) are the other units of activity; the values 108 and 104 do not define the rutherford.
The unit is named after Ernest Rutherford and is now obsolete, replaced by the becquerel, and 1 rutherford equals one million becquerels.
Which of the following institution is also known as the banker to all the banks in India?
Your Answer : (Not Answered)
Correct Answer : A
The Reserve Bank of India is known as the banker to all banks, because commercial banks keep their reserves with it and borrow from it as a last resort. The SBI is the largest commercial bank but does not hold the other banks' reserves, the Ministry of Finance is a government department, and the Central Bank of India is only a commercial bank. So the RBI is the answer.

Correct Answer : D
All three descriptions apply to photo-oxidation.
It is the light-driven and oxygen-driven breakdown of a substance, and it covers photorespiration, in which Rubisco fixes oxygen instead of carbon dioxide, and photolysis, the light-driven splitting of water.
Your Answer : (Not Answered)
Correct Answer : C
Because of surface tension.
Camphor dissolves unevenly around the fragment, lowering the surface tension of the water locally. The stronger pull from the untouched water on the other side drags the piece that way, and as the dissolution shifts, so does the direction - producing the darting motion.

Correct Answer : C
The element of an electric heater is made of nichrome.
The nickel-chromium alloy has high resistivity, so it dissipates a lot of heat for a modest current; a very high melting point, about 1,400 °C; and it forms a protective oxide layer, so it does not burn away when red-hot in air.

Correct Answer : A
Potassium nitrate is used as a fertiliser. It supplies both potassium and nitrogen, and unlike most nitrogen fertilisers it contains no chloride, so it suits salt-sensitive crops such as tobacco, citrus and potato.
Its nitrogen is already in the nitrate form plants take up directly. The same compound, saltpetre, is also the oxidiser in gunpowder.

Correct Answer : B
Protons and neutrons are held together in the nucleus by the strong nuclear force, carried by exchange particles - mesons in the older description, gluons in the modern one.
It is about a hundred times stronger than the electrostatic repulsion between protons, but acts only over about 10−15 m, which is why very large nuclei become unstable.

Correct Answer : B
Chemistry is called the central science, because it links the physical sciences to the life and applied sciences.
Physics explains why chemistry works, and chemistry in turn explains biology, geology and materials science - so it sits in the middle of the chain of explanation.
In India 'Teacher's Day' is observed on which of the date?
Your Answer : (Not Answered)
Correct Answer : D
Teachers' Day is observed on 5 September, the birthday of Dr S. Radhakrishnan.
When his students asked to celebrate his birthday in 1962, the philosopher-president suggested it be marked as Teachers' Day instead. World Teachers' Day is 5 October.

The Moortidevi Award was conferred on her.

The eye of a tropical cyclone is characterised by
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: Calm winds and clear skies
The eye at the centre of a mature tropical cyclone is remarkably calm, with light winds and often clear sky, typically 20 to 60 km across. It forms because air descends in the centre, and sinking air warms and suppresses cloud. Surrounding it is the eyewall, a ring of towering thunderstorms where the winds are strongest and the rain heaviest - the opposite of the eye in every respect, and the part of the storm that does most damage. This structure produces the notorious pattern experienced on the ground: violent conditions, then a sudden lull of perhaps half an hour as the eye passes, then a return of the worst winds from the opposite direction as the far side of the eyewall arrives. People who venture out during the lull are frequently caught by it. A well-defined, symmetrical eye is a sign of an intense storm; a ragged or filled-in eye indicates weakening.
