Question : A, B, and C are three angles of a triangle. If $A-B=45^{\circ}$ and $B-C=15^{\circ}$ then $\angle A=$?

Option 1: 83°

Option 2: 85°

Option 3: 95°

Option 4: 75°

Team Careers360 26th Jan, 2024

Correct Answer: 95°


Solution : Given, $A-B=45^{\circ}$
And $B-C=15^{\circ}$
So, $A=45^{\circ}+B$
And, $C=B-15^{\circ}$
By the angle sum property of a triangle,
$A+B+C=180^\circ$
⇒ $45^{\circ}+B+B+B-15^{\circ}=180^{\circ}$
⇒ $3B+30^\circ = 180^\circ$
⇒ $B = 50^\circ$
Now, $A=45^{\circ}+B= 45^{\circ}+50^\circ= 95^\circ$
Hence, the correct answer is $95^\circ$

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

Team Careers360 26th Jan, 2024

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,

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.
