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. 5.
Option 1: access
Option 2: entry
Option 3: approach
Option 4: ingress
Correct Answer: access
Solution : The first option is the correct choice.
Access means the ability or permission to enter, use, or retrieve something, such as information or a location, and is the appropriate choice in this context.
The meanings of the other options are as follows:
Question : D, E, and F are the midpoints of the sides BC, CA, and AB, respectively of a $\triangle ABC$. Then the ratio of the areas of $\triangle DEF$ and $\triangle ABC$ is:
Option 1: $\frac{1}{2}$
Option 2: $\frac{1}{4}$
Option 3: $\frac{1}{8}$
Option 4: $\frac{1}{16}$
Correct Answer: $\frac{1}{4}$
Solution : Given: D, E, and F are the midpoints of the sides BC, CA, and AB, respectively of a $\triangle ABC$.
$DF || BE$ and $DF = \frac{1}{2}BC$ Since the opposite sides of the quadrilateral are equal and parallel. So, BDFE is a parallelogram. Similarly, DFCE
Question : The carbon dioxide content in the air that we exhale is about
Option 1: 4 %
Option 2: 8 %
Option 3: 12 %
Option 4: 16 %
Correct Answer: 4 %
Solution : The correct option is - 4%
The amount of air that is inhaled has 21% oxygen and 0.04% carbon dioxide, whereas the amount of air that is expelled has 16% oxygen and 4% carbon dioxide. This is so because when we breathe, our cells
Question : Directions: From the given answer figures, select the one in which the question figure is hidden/embedded.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Because there is no restriction on the rotation of the figure, we will check all the possible angles where the question figure can fit itself in the given option figures. By comparison of all the option figures, the given question figure is embedded only in the
Question : Select the most appropriate option to substitute the underlined segment in the given sentence. If there is no need to substitute it, select “No substitution”. The prisoner was looking about an opportunity to escape.
Option 1: looking after
Option 2: looking up
Option 3: looking for
Option 4: No substitution
Correct Answer: looking for
Solution : The correct choice is the third option.
Explanation: The phrase "looking for" is commonly used when searching for something or someone. In this context, the prisoner is actively seeking an opportunity to escape, making "looking for" the most suitable choice.
Therefore, the correct sentence
Question : Directions: Select the option in which the numbers are related in the same way as the numbers of the following sets. (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.) (1056, 11, 16); (480, 10, 8)
Option 1: (88, 2, 7)
Option 2: (110, 3, 6)
Option 3: (384, 8, 4)
Option 4: (90, 3, 5)
Correct Answer: (90, 3, 5)
Solution : Given: (1056, 11, 16); (480, 10, 8)
Like, (1056, 11, 16)→(11 × 16) × 6 = 176 × 6 = 1056 (480, 10, 8)→(10 × 8) × 6 = 80 × 6 = 480
Let's check each option – First option: (88, 2,
Question : What is the value of $\frac{72}{22} \times \frac{11}{3} \div \frac{21}{9}$ of $\frac{18}{7} ?$
Option 1: 6
Option 2: 36
Option 3: 8
Option 4: 2
Correct Answer: 2
Solution : $\frac{72}{22} \times \frac{11}{3} \div \frac{21}{9}$ of $\frac{18}{7}$ = $\frac{792}{66} \div \frac{21}{9}$ of $\frac{18}{7}$ = $\frac{132}{11} \div \frac{378}{63}$ = $\frac{132}{11} \div \frac{42}{7}$ = $\frac{924}{462}$ = $\frac{6}{3}$ = 2 Hence, the correct answer is 2.
Question : Directions: Select the related set of letters from the given alternatives. STAR : TSRA :: ROSE : ?
