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 in 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. 3.
Option 1: migrate
Option 2: move
Option 3: stir
Option 4: jump
Correct Answer: move
Solution : The second option is the correct choice.
Move means to change one's location or position. Thus, it is the most appropriate choice in this context.
The meanings of the other options are as follows:
Question : Directions: Select the option that represents the letters that, when placed from left to right in the following blanks, will complete the letter series. MNB_CM_ _WCMNB_ _M_ _YC
Option 1: VNBXCNB
Option 2: VNBYDNB
Option 3: WYYYCNB
Option 4: WNBYDNB
Correct Answer: VNBXCNB
Solution : Given: MNB_CM_ _WCMNB_ _M_ _YC
To fill the series we have to divide the series – MNB_C / M_ _WC / MNB_ _ / M_ _YC
Let's check each option – First option: VNBXCNB; MNBVC / MNBWC / MNBXC /
Question : Directions: In the following question, from the given alternative words, select the word that cannot be formed using the letters of the given word. CALCULATE
Option 1: CAT
Option 2: TEA
Option 3: LATE
Option 4: TEAM
Correct Answer: TEAM
Solution : Given: CALCULATE
Now, let's compare all the option words with the word CALCULATE – First option: CAT; All the letters of CAT are present in the word CALCULATE. Second option: TEA; All the letters of TEA are present in the word CALCULATE. Third option: LATE;
Question : Directions: If R ÷ S means that R is the mother of S, R × S means that R is the father of S and R – S means that R is the sister of S, then which of the following expressions shows that P is the father of R?
Option 1: P × Q ÷ R
Option 2: Q × P – R
Option 3: R × Q – P
Option 4: P × Q – R
Correct Answer: P × Q – R
Solution : Let's check the options – First option: P × Q ÷ R According to the given expression, the family tree will be as follows – Here, the quadrilateral represents the male, and the circular figure represents the female in the figure.
Question : Directions: Town C is to the south of Town A. Town D is to the west of Town A. Town B is to the east of Town D. Town M is to the south of Town B and south-east of Town C. What is the position of town A with respect to town B?
Option 1: East
Option 2: West
Option 3: North
Option 4: South
Correct Answer: West
Solution : Firstly, we will draw the diagram as per the given instructions –
So, from the above diagram, A is in the west direction concerning B's position. Hence, the second option is correct.
Question : If $2A=3B$, then what is the value of $\frac{A+B}{A}$?
Option 1: $\frac{5}{4}$
Option 2: $\frac{2}{3}$
Option 3: $\frac{5}{2}$
Option 4: $\frac{5}{3}$
Correct Answer: $\frac{5}{3}$
Solution : Given: $2A=3B$ ⇒ $\frac{A}{B}=\frac{3}{2}$ Let, $A=3k,B=2k$ $\frac{A+B}{A}=\frac{3k+2k}{3k}=\frac{5}{3}$ Hence, the correct answer is $\frac{5}{3}$.
Question : A single discount equivalent to three successive discounts of 8%, 15% and 12% is:
Option 1: 17.5%
Option 2: 68.816%
Option 3: 35%
Option 4: 31.184%
Correct Answer: 31.184%
Solution : The successive discounts are 8%, 15% and 12%. Let the initial value be 100. Discounted value = (100 – 8)% of (100 – 15)% of (100 – 12)% of 100 = 92% of 85% of 88% of 100 = $\frac{92}{100} × \frac{85}{100} × \frac{88}{100} ×
Question : In a circle with a radius 20 cm, P is a point located at a distance of y cm from the centre of the circle. If the length of a tangent drawn from point P to the circle is 21 cm, find the value of y.
Option 1: 31 cm
Option 2: 28 cm
Option 3: 29 cm
Option 4: 25 cm
Correct Answer: 29 cm
Solution : Given that OP = y cm, QP = 21 cm, OQ = 20 cm. To find the length of OP, apply Pythagoras theorem in $\triangle$OPQ. ⇒ OQ2 + QP2 = OP2 ⇒ 202 + 212 = y2 ⇒
Question : Directions: Select the figure from the given options that can replace the question mark (?) and complete the pattern.

Question : A sum was doubled with a 12.5% rate of simple interest per annum. Then time taken for that sum to be doubled is:
Option 1: $8\frac{1}{2}$ years
Option 2: 8 years
Option 3: 10 years
Option 4: $12\frac{1}{2}$ years
Correct Answer: 8 years
Solution : Let the principal be $P$. Sum = $2P$ Let the time be $T$. $\therefore$ Simple interest = Amount – Principal = $2P-P=P$ We know, Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ ⇒ $T=\frac{P×100}{P×12.5}$ ⇒ $T=\frac{1000}{125}$ $\therefore T$ = 8 years Hence, the correct
