Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (2, 9, 85); (3, 9, 90) (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.)
Option 1: (7, 23, 130)
Option 2: (7, 9, 130)
Option 3: (13, 9, 130)
Option 4: (12, 9, 130)
Correct Answer: (7, 9, 130)
Solution : Given: (2, 9, 85); (3, 9, 90)
The pattern is as follows – (2, 9, 85)→22 + 92 = 4 + 81 = 85 (3, 9, 90)→32 + 92 = 9 + 81 = 9 Let's check the options
Question : In a particular trophic level, how is the standing crop measured?
Option 1: As biomass
Option 2: As gross productivity
Option 3: As net productivity
Option 4: As pyramid of energy
Correct Answer: As biomass
Solution : The correct option is biomass.
Biomass can be quantified by weighing the total dry weight of all organisms in that trophic level per unit area. These measurements help ecologists assess the amount of living material or energy present at each trophic level.
Question : Study the below pie chart and answer the question the following question: If the pie chart shows the distribution of 36 marbles among 3 persons, then the number of marbles Madhuri has is:
Option 1: 12
Option 2: 8
Option 3: 16
Option 4: 18
Correct Answer: 18
Solution : Given: The pie chart shows the distribution of 36 marbles among 3 persons. In 360°, 36 marbles are distributed. So, in 1°, number of marbles = $\frac{36}{360°}$. Then, the number of marbles Madhuri has is $\frac{36}{360°}$ × 180° = 18 marbles Hence, the correct answer
Question : Identify the segment in the sentence which contains a grammatical error. If there is no error, select 'No error'.
If you study hard, you surely got selected for the scholarship.
Option 1: for the scholarship.
Option 2: you surely got selected
Option 3: No error
Option 4: If you study hard
Correct Answer: you surely got selected
Solution : The second option is correct.
Question : Directions: Rita travelled 35 km from a point towards the south and then turned left and travelled 20 km and finally turned left again and travelled 35 km. In which direction is she from the starting point?
Option 1: East
Option 2: West
Option 3: North
Option 4: South
Correct Answer: East
Solution : Firstly, we will draw the diagram as per the given instructions – Now, we have to find in which direction is Rita from the starting point.
Here A is the starting position and D is the end point.
So, Rita is in the east direction
Question : What is the product formed when CH3CH2OH reacts with O2?
Option 1: H2O+ heat
Option 2: CO2 + H2O + heat and light
Option 3: CO2 + H2O
Option 4: CO2 + heat and light
Correct Answer: CO2 + H2O + heat and light
Solution : The correct option is CO2 + H2O + heat and light.
When Ethanol (CH3CH2OH) reacts with oxygen (O2) in the presence of a suitable catalyst, combustion
Question : An arc on a circle, whose length is 19.25 cm, subtends an 18° angle at the centre. What is the area of the circle? [Use $\pi = \frac{22}{7}$]
Option 1: 11796.625 cm2
Option 2: 11786.625 cm2
Option 3: 11780.625 cm2
Option 4: 11790.625 cm2
Correct Answer: 11790.625 cm2
Solution : Here, $2 × \pi × r × \frac{\theta }{360°} = 19.25$ Where $r$ is the radius and $\theta$ is the central angle of the arc. ⇒ $2 × \frac{22}{7} × r × \frac{18 }{360} = 19.25$ ⇒ $r = \frac{35 × 7}{4} =
Question : From 40 metres away from the foot of a tower, the angle of elevation of the top of the tower is 60°. What is the height of the tower?
Option 1: $\frac{120}{\sqrt{3}}$ m
Option 2: $\frac{60}{{\sqrt3}}$ m
Option 3: $\frac{50}{{\sqrt3}}$ m
Option 4: $\frac{130}{{\sqrt7}}$ m
Correct Answer: $\frac{120}{\sqrt{3}}$ m
Solution : Let height of the tower = $h$ m From the figure, $\tan 60°=\frac{h}{40}$ ⇒ $\sqrt{3}=\frac{h}{40}$ ⇒ $h=40\sqrt{3}$ m Rationalising we get, ⇒ $ h =40\sqrt{3} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{120}{\sqrt{3}}$ m Hence, the correct answer is $\frac{120}{\sqrt{3}}$ m.
