Option 1: DCBA
Option 2: ACBD
Option 3: CABD
Option 4: BACD
Correct Answer: DCBA
Solution : The correct choice is the first option: DCBA.
The logical flow of sentences is as follows:
Sentence D: This sentence introduces the theme, focusing on the observation of babies being loud-throated.
Sentence C: This sentence provides additional details about the behaviour of babies, creating a
Question : If 60% of the students in a school are boys and the number of girls is 812, how many boys are there in the school?
Option 1: 1128
Option 2: 1218
Option 3: 1821
Option 4: 1281
Correct Answer: 1218
Solution : Let the total number of students be $x$. Boys = 60% Girls = 40% According to the question, $\frac{40x}{100} = 812$ $\therefore x = 2030$ The total number of students = 2030 Now, number of boys = (total number of students – number of girls)
Question : At low temperatures, lead behaves as a:
Option 1: semiconductor
Option 2: superconductor
Option 3: insulator
Option 4: conductor
Correct Answer: superconductor
Solution : The correct option is a superconductor.
At low temperatures of 7.2 Kelvin, lead exhibits phase transitions towards superconductivity. In 1913, this finding was made. Lead's electrical resistivity falls to zero at this temperature, sometimes referred to as the critical temperature. The transition is so abrupt
Question : In the given figure, ABC is a right-angled triangle, $\angle$ABC = 90° and $\angle$ACB = 60°. If the radius of the smaller circle is 2 cm, then what is the radius (in cm) of the larger circle?
Option 1: 4
Option 2: 6
Option 3: 4.5
Option 4: 7.5
Correct Answer: 6
Solution : Given: ABC is a right-angled triangle. $\angle$ABC = 90°, $\angle$ACB = 60°, and the radius of the smaller circle is 2 cm. $\angle$ACB = 60° so, $\angle$ACP = $\angle$PCB = 30° In $\triangle$CPD, $\sin30°=\frac{PD}{CP}$ ⇒ CP = 2 × 2 = 4 cm In $\triangle$CQE,
Question : The midpoints of AB and AC of a $\triangle ABC$ are X and Y, respectively. If BC + XY = 18 cm, then the value of BC – XY is:
Option 1: 12 cm
Option 2: 6 cm
Option 3: 8 cm
Option 4: 4 cm
Correct Answer: 6 cm
Solution :
In $\triangle ABC$, $XY\parallel BC$ and $XY = \frac{1}{2}BC$. Given: $BC + XY = 18$ cm So, $BC + \frac{1}{2}BC = 18$ ⇒ $BC = \frac{18}{1.5} = 12$ The length of $BC$ is 12 cm. $BC - XY = BC - \frac{1}{2}BC = \frac{1}{2}BC$
Question : Directions: The bar chart given below shows the percentage distribution of the production of various models of mobile manufacturing in 2007 and 2008. The total production in 2007 was 35 lakh mobile phones, and in 2008, the production was 44 lakh. Study the chart and answer the following questions:
If the percentage production of A type mobiles in 2008 was the same as that in 2007, then the number of A type mobiles produced in 2008 would have been:
Option 1: 14,00,000
Option 2: 13,20,000
Option 3: 11,70,000
Option 4: 10,50,000
Correct Answer: 13,20,000
Solution : As per the given graph, The total production of mobile phones in 2008 = 44 lakh The percentage of mobile of model A manufactured in 2007 = 30% The required percentage = 30% of 44 lakh = 13,20,000 Hence, the correct answer is 13,20,000.
Question : Directions: A man walks 7 km towards the south and turns to the left. After walking 5 km, he turns to the right and walks 7 km. In which direction is he now from the starting point?
Option 1: West
Option 2: South
Option 3: South-East
Option 4: North-East
Correct Answer: South-East
Solution : Firstly, we will draw the diagram according to the instructions given in the question – Now, we have to find the direction of the end point from the starting point. So, he is in the southeast direction from the starting point. Hence, the third option
Question : The ratio of the two numbers is 6 : 7 and their HCF is 3. Their LCM is _____.
Option 1: 124
Option 2: 128
Option 3: 122
Option 4: 126
Correct Answer: 126
Solution : Ratio = 6 : 7 HCF = 3 First number = $6\times 3 = 18$ Second number = $7\times 3 = 21$ So, LCM of 18 and 21 = 3 × 6 × 7 = 126 Hence, the correct answer is 126.
