Question : Which actinide, discovered by Glenn T. Seaborg in 1940, is used as a heat source for sensitive electrical components in satellites as well as a power source for satellites?
Option 1: Curium
Option 2: Plutonium
Option 3: Nobelium
Option 4: Americium
Correct Answer: Plutonium
Solution : The correct option is Plutonium.
Plutonium-238, an Actinide discovered by Glenn T. Seaborg in 1940, is utilised as both a power source and a heat source for delicate electrical components in spacecraft. With thermoelectric generators, the heat generated during the radioactive breakdown of Pu-238 can
Question : The centroid of a $\triangle ABC$ is G. The area of $\triangle ABC$ is 60 cm2. The area of $\triangle GBC$ is:
Option 1: 10 cm2
Option 2: 30 cm2
Option 3: 40 cm2
Option 4: 20 cm2
Correct Answer: 20 cm2
Solution : The area of triangle GBC is one-third of the area of $\triangle ABC$. Given that the area of $\triangle ABC$ is 60 cm2. The area of $\triangle GBC=\frac{1}{3} \times 60 = 20$ cm2 Hence, the correct answer is 20 cm
Question : Directions: Select one of the option figures that is embedded in the given figure (rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : The embedded figure will have the same orientation as the main figure. Only the third option figure is embedded in the given figure.
Hence, the third option is correct.
Question : Directions: Select the figure that will come next in the following series.
Solution : Here, the pattern is as follows – 1. In each figure, the circle is rotating by 90° and also moving corner by corner in an anti-clockwise direction. 2. In each figure the arrow mark figure is rotating by 90° in a clockwise direction and moving side
Question : Select the most appropriate option that can substitute the underlined segment in the given sentence.
Abhijeet feels extremely tired after working all day long.
Option 1: depressed
Option 2: exhausted
Option 3: sleepy
Option 4: bare
Correct Answer: exhausted
Solution : The correct choice is the second option.
Exhausted is the word that describes someone who feels extremely tired after a long day of work, as it directly conveys the idea of physical fatigue and weariness.
The meanings of the other options are as follows:
Question : In the given figure, chords XY and PQ intersect each other at point L. Find the length of XY (in cm).
Option 1: 21
Option 2: 20
Option 3: 22
Option 4: 23
Correct Answer: 22
Solution : Given: PQ = 10 cm, QL = 5 cm, YL = 3 cm, and LX = (x + 3) cm. LQ × LP = LY × LX Placing the values in the above formula, 5 × 15 = 3 × (x + 3) ⇒ 75
Question : At what point does the line $3x+y=-6$ intercept the x-axis?
Option 1: (2, 0)
Option 2: (–2, 0)
Option 3: (0, –6)
Option 4: (0, 6)
Correct Answer: (–2, 0)
Solution : At an x-intercept, y = 0. So, 3x + 0 = – 6 Solving for x, ⇒ 3x = – 6 ⇒ x = – 2 So, the required intercept point = (–2, 0) Hence, the correct answer is (–2, 0).
Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".
He was for all (1) / selling the car (2) / and buying a bicycle. (3) / No Error (4)
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : The error lies in the first part of the sentence.
The phrase "he was for all" is not the correct structure in English. The correct expression would be, "he was in favour of" or simply "He was all for" followed by a noun or pronoun.
Question : The length of each side of a triangle is 12 cm. What is the length of the circumradius of the triangle?
Option 1: $8 \sqrt{3} \mathrm{~cm}$
Option 2: $2 \sqrt{3} \mathrm{~cm}$
Option 3: $6 \sqrt{3} \mathrm{~cm}$
Option 4: $4 \sqrt{3} \mathrm{~cm}$
Correct Answer: $4 \sqrt{3} \mathrm{~cm}$
Solution : The length of each side of a triangle is 12 cm. So, it is an equilateral triangle. $\therefore$ Circumradius of a equilateral triangle $= \frac{\text{Side Length}}{\sqrt{3}} = \frac{12}{\sqrt{3}}= 4\sqrt{3} \mathrm{~cm}$ Hence, the correct answer is $4\sqrt{3} \mathrm{~cm}$.
Question : Directions: In the following question, find the odd letter cluster from the given alternatives.
Option 1: ACEG
Option 2: IKMO
Option 3: FHJL
Option 4: TUWY
Correct Answer: TUWY
Solution : Let's check the options – First option: ACEG; A + 2 = C; C + 2 = E; E + 2 = G Second option: IKMO; I + 2 = K; K + 2 = M; M + 2 = O Third option: FHJL; F
