Question : The fuel used in an atomic reactor is
Option 1: Coal
Option 2: Petrol
Option 3: Combustable gases
Option 4: Uranium
Correct Answer: Uranium
Solution : The correct option is Uranium.
The fuel used in an atomic reactor, also known as a nuclear reactor, is uranium or plutonium. These elements undergo a controlled nuclear reaction, in which the nucleus of an atom is split, releasing a large amount of energy in the form of heat. This heat is then used to produce steam, which drives turbines connected to generators, ultimately producing electricity.

Question : A can do as much work in 4 days as B can do in 5 days and B can do as much work in 6 days as C in 7 days. In what time will C complete a piece of work that A can do in a week?
Option 1: $10\frac{5}{24}$ days
Option 2: $4\frac{4}{5}$ days
Option 3: $6\frac{8}{15}$ days
Option 4: $12\frac{6}{19}$ days
Correct Answer: $10\frac{5}{24}$ days
Solution : A's 4-day work = B's 5-day work The ratio time is taken by A and B = 4 : 5 B's 6-day work = C's 7-day work The ratio of time taken by B and C = 6 : 7 Combining the two ratios, we get: The ratio of time taken by A, B and C, A : B : C = 4 × 6 : 5 × 6 : 7 × 5 = 24 : 30 : 35 The ratio efficiency of A : B : C = $\frac{1}{24}:\frac{1}{30}:\frac{1}{35} = 35:28:24$ Let one day's work of A, B, and C be 35, 28 and 24 units. 7 days work of A = $7\times 35 = 245$ units 245 units completed by C = $\frac{245}{24}=10\frac{5}{24}$ Hence, the answer is $10\frac{5}{24}$ days.
Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank. Any (1) _____ that revolves around a planet is a satellite. Mother Earth has a natural satellite on the moon. The Earth is circled by a lot of man-made or artificial satellites. In 1957, the Soviet Sputnik was the first to be (2) _____ into space. There are currently a number of artificial satellites launched into space by various nations. These satellites make it possible for us to talk on the phone, watch television, predict the weather, map the various surfaces of the earth and learn more about the world in which we live. How does a satellite get started? It is typically launched into space by means of a rocket. After ascending into the thinner air layers above the earth, the satellite is released from the rocket. For a successful satellite launch, a rocket's speed is carefully calculated and controlled. Every object in space is pushed towards the Earth's centre by gravity. The inertia of motion will propel the object into space if it has its own velocity of motion. When the orbital velocity is exactly right, these two opposing forces are balanced, causing the satellite to (3) _____ towards the earth while still hovering over its surface. earth in a 24-hour period; It doesn't change when compared to a point on the surface of the earth. These orbits are typically used by satellites for communication and weather. The camera on the weather satellites takes pictures and sends them back to Earth. These are helping aid in weather forecasting. Radio receivers and amplifiers on communication satellites can (4) _____ waves back at a frequency that is different from the one the satellite received. The beaming frequencies of satellites that are 'parked' too close to one another must not interfere with one another. Television signals can be transmitted from one location to another using broadcast satellites, and scientists can (5) _____ scientific data from numerous satellites. Select the most appropriate option to fill in the blank no.2.
Option 1: lobbed
Option 2: launched
Option 3: floated
Option 4: tossed
Correct Answer: launched
Solution : The correct choice is the second option.
Launched refers to starting or setting something in motion, as in launching a rocket or a satellite.
The meanings of the other options are as follows:
Therefore, the correct sentence is: "In 1957, the Soviet Sputnik was the first to be launched into space."
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold part at 1, 2 and 3 that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).
I hope you will be able to steer ahead of the will anti-social elements.
(1) steer clear
(2) steer free
(3) steer out
(4) No Improvement
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : The correct improvement for the sentence is: steer clear.
Explanation: The phrase "steer clear" means to avoid or stay away from something, especially something undesirable or harmful, which is the intended meaning in this context. It is a common and idiomatic expression.
steer free
steer out
Question : Select the correct active form of the given sentence. The catch should not be dropped.
Option 1: Don’t drop the catch.
Option 2: You would not drop the catch.
Option 3: Have you dropped the catch?
Option 4: Let the catch not be dropped.
Correct Answer: Don’t drop the catch.
Solution : The correct choice is the first option.
Active voice emphasises the doer of the action, while passive voice emphasises the receiver. To convert passive to active, we make the subject perform the action and rephrase the verb.
The structure of the active sentence in the case of the imperative sentence is: "Don't + base form of the verb + object."
Therefore, the active voice would be: "Don't drop the catch."
Question : Select the most appropriate ANTONYM of the underlined word. The dacoits ravaged the bungalow in the absence of its owner.
Option 1: Exploded
Option 2: Demolished

Solution : The third option is the correct choice.
Ravaged implies severe damage or destruction caused by the dacoits, indicating a state of ruin or disorder. On the other hand, restored means to bring something back to its original or former condition.
Exploded means to burst forth violently, often with a release of energy.
Demolished means to completely destroy or ruin.
Sealed means to close or secure tightly.
Therefore, the correct answer is restored.
Question : Directions: In the following question, you have to identify the correct response from the given premises stated according to the following signs. If × means addition, – means division, ÷ means subtraction, and + means multiplication, then which of the equations is correct?
Option 1: 16 × 5 ÷ 10 + 4 – 3 = 19
Option 2: 16 + 5 ÷ 10 × 4 – 3 = 9
Option 3: 16 + 5 – 10 × 4 ÷ 3 = 9
Option 4: 16 – 5 × 10 ÷ 4 + 3 = 12
Correct Answer: 16 + 5 – 10 × 4 ÷ 3 = 9
Solution : Given: × means addition, – means division, ÷ means subtraction, and + means multiplication.
Replace the mathematical signs in the equations and solve the equations one by one. Let's check the given options – First option: 16 × 5 ÷ 10 + 4 – 3 = 19 ⇒ 16 + 5 – 10 × 4 ÷ 3 = 19 Solving L.H.S. of the equation – = 16 + 5 – 10 × 1.33 = 16 + 5 – 13.33 = 21 – 13.33 = 7.67 ≠ 19 Second option: 16 + 5 ÷ 10 × 4 – 3 = 9 ⇒ 16 × 5 – 10 + 4 ÷ 3 = 9 Solving L.H.S. of the equation – = 16 × 5 – 10 + 1.33 = 80 – 10 + 1.33 = 81.33 – 10 = 71.33 ≠ 9 Third option: 16 + 5 – 10 × 4 ÷ 3 = 9 ⇒ 16 × 5 ÷ 10 + 4 – 3 = 9 Solving L.H.S. of the equation – = 16 × 0.5 + 4 – 3 = 8 + 4 – 3 = 12 – 3 = 9 = R.H.S. Fourth option: 16 – 5 × 10 ÷ 4 + 3 = 12 ⇒ 16 ÷ 5 + 10 – 4 × 3 = 12 Solving L.H.S. of the equation – = 3.2 + 10 – 4 × 3 = 3.2 + 10 – 12 = 13.2 – 12 = 1.2 ≠ 12
So, only the third option satisfies the given condition. Hence, the third option is correct.
