Question : The value of $\frac{0.325 \times 0.325+0.175 \times 0.175+25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}-\frac{0.5}{1.5}$ is:

Option 1: –3

Option 2: 3

Option 3: –1

Option 4: 0

Team Careers360 21st Jan, 2024

Correct Answer: 3


Solution : $\frac{0.325 \times 0.325+0.175 \times 0.175+25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}-\frac{0.5}{1.5}$
$=\frac{0.325^2+0.175^2+2 \times 0.325 \times0.175}{0.325^2-0.175^2}-\frac{0.5}{1.5}$
$=\frac{(0.325+0.175)^2}{(0.325+0.175)(0.325-0.175)}-\frac{0.5}{1.5}$
$=\frac{(0.325+0.175)}{(0.325-0.175)}-\frac{0.5}{1.5}$
$=\frac{(0.5)}{(0.15)}-\frac{0.5}{1.5}$
$=\frac{10}{3}-\frac{1}{3}$
$=3$
Hence, the correct answer is 3.

Question : Improve the underlined part of the sentence. Choose 'No improvement' as an answer if the sentence is grammatically correct.
This has sharp decreased the cases of water-borne diseases.

Option 1: sharp decrease

Option 2: sharply decreased

Option 3: sharper decreases

Option 4: No improvement

Team Careers360 22nd Jan, 2024

Correct Answer: sharply decreased


Solution : The second option is correct.

  • The adverb sharply correctly modifies the verb decreased to indicate the extent of the decrease.
  • The original sentence incorrectly uses the adjective sharp instead of the adverb.
  • Adjectives describe nouns, while adverbs describe verbs, adjectives, and other adverbs.

Question : Comprehension:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the surface where the earthquake starts is called the hypocenter and the location directly above it on the surface of the earth is called the epicentre.

Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until a larger earthquake happens. The largest main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the main shock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

The Earth has four major layers: the inner core, outer core, mantle, and crust. The crust and the top of the mantle make up a thin skin on the surface of our planet.

But this skin is not all in one piece; it is made up of many pieces, like a puzzle covering the surface of the earth. Not only that, but these puzzle pieces keep slowly moving around, sliding past one another, and bumping into each other. We call these puzzle pieces tectonic plates, and the edges of the plates are called plate boundaries. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults, and there is an earthquake.

Question:

Which of the following words is the ANTONYM of the word 'boundaries' used in the passage?

Option 1: Cores

Option 2: Verges

Option 3: Rims

Option 4: Brinks

Team Careers360 24th Jan, 2024

Correct Answer: Cores


Solution : The correct choice is the first option.

According to the passage, cores can be the appropriate choice of antonym from the given words, as boundaries refer to the thin skin on the surface, whereas cores refer to the inner dense part of the Earth.

Question : In measuring the sides of a rectangle, there is an excess of $5\%$ on one side and $2\%$ deficit on the other. Then the error percentage in the area is:

Option 1: $3.3\%$

Option 2: $3\%$

Option 3: $2.9\%$

Option 4: $2.7\%$

Team Careers360 14th Jan, 2024

Correct Answer: $2.9\%$


Solution : Let the original sides be $\mathrm{a}$ and $\mathrm{b}$.
Initial area, $\mathrm{A_\text{initial}=ab}$
There is an excess of $5\%$ on one side.
The new length of this side $=\mathrm{1.05a}$
There is a deficit of $2\%$ on the other side.
The new length of this side $=\mathrm{0.98b}$

Question : A sum amounts to INR 7,562 in 4 years and to INR 8,469.44 in 5 years at a certain rate per annum, when the interest is compounded yearly. The rate of interest is:

Option 1: 12%

Option 2: 15%

Option 3: 20%

Option 4: 8%

Team Careers360 18th Jan, 2024

Correct Answer: 12%


Solution : Let $P$ be the principal sum and $R$ be the interest rate.
Total amount after $n$ years, compounded annually = $P(1+\frac{R}{100})^n$
Total amount after 4 years = INR 7,562
$P(1+\frac{R}{100})^4=7562$ -------------(i)
Total amount after 5 years = INR 8,469.44
$P(1+\frac{R}{100})^5=8469.44$ -------------(ii)
Dividing (ii) by (i),
