Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Based on above table, choose the wrong statement :
Your Answer : (Not Answered)
Correct Answer : D
The wrong statement is total number of patients was 200.
Add the six days:
\[ 25 + 38 + 45 + 18 + 36 + 39 = 201 \]
The other statements are correct: the range is \(45 - 18 = 27\); the number exceeded 30 on four of the six days (Tuesday, Wednesday, Friday, Saturday); and the Monday-Wednesday difference is \(45 - 25 = 20\).
In a three-digit number the digits add to 16, the hundreds digit is three times the units digit, and the tens digit is one more than the units digit. The number is:
Your Answer : (Not Answered)
Correct Answer : C
Let the units digit be \(u\). Then the hundreds digit is \(3u\) and the tens digit is \(u + 1\). Their sum is \(3u + (u+1) + u = 5u + 1 = 16\), so \(u = 3\), the tens digit is 4 and the hundreds digit is 9. The number is 943.
A single die is rolled. The probability of getting 1 or an even number is
Your Answer : (Not Answered)
Correct Answer : B
The favourable outcomes are 1 together with the even numbers 2, 4 and 6.
\[ \{1, 2, 4, 6\} \rightarrow 4 \text{ outcomes} \]
\[ P = \frac{4}{6} = \frac{2}{3} \]
1 is odd, so it does not overlap with the even numbers and nothing has to be subtracted - counting only three outcomes would leave 1 out.
Pipe P can fill a tank in 4 hours, pipe Q in 8 hours and pipe R in 24 hours. If all the pipes are open, in how many hours will the tank be filled?
Your Answer : (Not Answered)
Correct Answer : B
Work in rates: a pipe that fills a tank in \( n \) units of time fills \( \tfrac{1}{n} \) of it per unit, and rates add (an emptying pipe counting negative).
\[ \frac{1}{4} + \frac{1}{8} + \frac{1}{24} = \frac{6 + 3 + 1}{24} = \frac{10}{24} = \frac{5}{12} \]
\[ t = \frac{12}{5} = 2.4 \text{ hours} \]
A cistern has two taps attached to it. Tap B can empty the cistern in 45 minutes. But Tap A can fill the cistern in just 30 minutes. Rohit started both taps unknowingly but realized his mistake after 30 minutes. He immediately closed Tap B. Now after this, in how much time will the cistern be filled?
Your Answer : (Not Answered)
Correct Answer : D
Work in rates: a pipe that fills a tank in \( n \) units of time fills \( \tfrac{1}{n} \) of it per unit, and rates add (an emptying pipe counting negative).
For the first 30 minutes both taps run:
\[ \frac{1}{30} - \frac{1}{45} = \frac{3 - 2}{90} = \frac{1}{90} \text{ per minute} \]
\[ 30 \times \frac{1}{90} = \frac{1}{3} \text{ filled} \]
With Tap B closed, the remaining \( \tfrac{2}{3} \) is filled at \( \tfrac{1}{30} \) per minute:
\[ \frac{2}{3} \times 30 = 20 \text{ minutes} \]
The least multiple of 7, which leaves a remainder of 4, when divided by 6, 9, 15 and 18 is:
Your Answer : (Not Answered)
Correct Answer : D
L.C.M. of 6, 9, 15 and 18 is 90.
Let required number be \(90k + 4\), which is multiple of \(7\).
Least value of k for which \((90k + 4)\) is divisible by \(7\) is \(k = 4.\)
Required number,
\(= (90 \times 4) + 4\)
\(= 364\)

Each of the following questions is based on the following information:
a) Six flats on a floor in two rows facing North and South are allotted to P, Q, R, S, T and U.
b) Q gets a North facing flat and is not next to S.
c) S and U get diagonally opposite flats.
d) R next to U, gets a south facing flat and T gets North facing flat.
Which of the following combination get south facing flats?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: URP
Working the conditions through: Q and T face north and R faces south; R is next to U, so U faces south too; S is diagonally opposite U and therefore faces north, which leaves P facing south. Q may not be next to S, so the north row runs S, T, Q and the south row P, R, U, with S and U at opposite corners.
The south-facing row holds U, R and P.

Your Answer : (Not Answered)
Correct Answer : B
The different pair is 14 - 2744.
In the other pairs the second number is the cube of the first plus 3: 163 + 3 = 4096 + 3 = 4099, 133 + 3 = 2197 + 3 = 2200 and 113 + 3 = 1331 + 3 = 1334. For 14 the cube is 2744 itself, with nothing added.
So 14 - 2744 does not follow the rule shared by the other three pairs.
You can also see this by comparing each second number with the cube of the first: 16 cubed is 4096, 13 cubed is 2197 and 11 cubed is 1331, and each pair is 3 above the cube. For 14, the cube is 2744, exactly the second number, so this pair does not add 3 and is the odd one out.

Your Answer : (Not Answered)
Correct Answer : A
Correct answer: QRPS
The sentence reads:
The decomposers help in decomposing the dead bodies of plants and animals and hence help to clean the environment and put back various useful elements into soil, air and water.
Q gives the verb and R its object, so the two cannot be separated. P and S are then the two consequences, joined in turn by and hence and and.

Your Answer : (Not Answered)
Correct Answer : B
It is safety.
Security is freedom from danger, from the Latin se-cura, without care. Boldness, fearlessness and confidence describe the feeling rather than the condition.
Your Answer : (Not Answered)
Correct Answer : B
It is rose.
A rose is the flower. Rows are lines of things, and roes are fish eggs or small deer - rose and rows are pronounced alike.
Computer Awareness [ Question No: 12 To 14 ] :
A bridge has access to which address of a station on the same network ?
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: Physical
A bridge works at the data link layer, so the addresses it reads and learns are the physical, or MAC, addresses in the frame header. Network addresses are inside the payload, where a bridge does not look.
A human cannot feel a static discharge as high as _____ volts.
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: 200
A person begins to feel a static discharge at around three thousand volts, so 200 V passes entirely unnoticed - while being several times what it takes to damage a chip.

Your Answer : (Not Answered)
Correct Answer : C
Correct answer: Program
A program is the sequence of instructions, written in a computer language, that produces the desired result when executed. An algorithm is the method it implements, expressed independently of any language, and a decision table sets out conditions and actions as a design document.
General Awareness / General Knowledge (GK) [ Question No: 15 To 20 ] :
What is the 'Manhattan Project'?
Your Answer : (Not Answered)
Correct Answer : A
The Manhattan Project was a research and development undertaking that produced the first nuclear weapons.
Run by the United States with the United Kingdom and Canada during the Second World War, under General Leslie Groves with J. Robert Oppenheimer as director of the Los Alamos laboratory, it produced the first atomic bomb, tested at Trinity in July 1945, and the bombs dropped on Hiroshima and Nagasaki.
It was named after the Manhattan Engineer District of the US Army Corps of Engineers, not because it was a real estate venture, an art auction or a theme park in New York.

Correct Answer : D
RADAR is used for detecting and locating objects such as aircraft.
A pulse of radio waves is transmitted and the echo timed, giving the range as \(d = ct/2\); the antenna's direction gives the bearing, and the Doppler shift gives the speed. Radio waves do not travel through sea water, so submerged submarines are found by sonar.
Your Answer : (Not Answered)
Correct Answer : C
Oxygen is the most abundant element in the earth's crust, making up about 46 per cent by mass.
Silicon follows at about 28 per cent, aluminium at 8 per cent, iron at 5 per cent and calcium at 4 per cent. Most crustal rock is silicate, which is why the first two dominate.
