Staff Selection Commission Combined Higher Secondary Level Exam
Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given sets. (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.) (133, 144, 288) (127, 138, 276)
Option 1: (169, 180, 360)
Option 2: (143, 156, 312)
Option 3: (157, 168, 326)
Option 4: (117, 128, 266)
Correct Answer: (169, 180, 360)
Solution : Given: (133, 144, 288) (127, 138, 276)
Add 11 to the first number, to get the second number, and multiply the second number by 2, to get the third number. (133, 144, 288)→133 + 11 = 144; 144 × 2 = 288 (127,
Question : Directions: Select the Venn diagram that best represents the relationship between the following classes. Fathers, Teachers, Males
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Based on the general information, all the fathers are males. They can't be females. So, the circle that represents fathers will lie inside the circle that represents males. Also, some fathers can be teachers and some males can also be teachers and vice versa. So, the
Question : A sells a cycle to B at a profit of 33% and B sells it to C at a loss of 25%. If C bought the cycle for INR 3059, then the cost price of it for A was:
Option 1: INR $3066 \frac{2}{3}$
Option 2: INR $2044 \frac{1}{3}$
Option 3: INR $4054 \frac{1}{3}$
Option 4: INR $5014 \frac{2}{3}$
Correct Answer: INR $3066 \frac{2}{3}$
Solution : Selling price of B = 3059 Loss = 25% of cost price 75% of the cost price of B = 3059 The cost price of B = $\frac{3059}{0.75}$ = the selling price of A Profit = 33% of the cost price of A
Question : Which of the following is the proper number of electrons in 1 A of current?
Option 1: 6.25 × 1021
Option 2: 6.25 × 1018
Option 3: 6.25 × 1019
Option 4: 6.25 × 1015
Correct Answer: 6.25 × 1018
Solution : The correct answer is 6.25 × 1018.
When a wire allows the flow of 1 Coulomb of charge in 1 second, the resulting current through the wire is 1 Ampere, expressed by the formula I = Q/t.
This relationship signifies
Question : Directions: How many triangles are there in the given figure?
Option 1: 8
Option 2: 10
Option 3: 9
Option 4: 7
Correct Answer: 9
Solution : The given figure can be labelled as shown below –
Now, in the above figure, there are a total of 9 triangles. They are ABG, BGF, BHF, BHC, FGH, DEH, DEG, DGH, and BGH.
Hence, the third option is correct.
Question : Choose the word that is opposite in meaning to the given word. Young
Option 1: Limited
Option 2: Silly
Option 3: Mature
Option 4: Gravity
Correct Answer: Mature
Solution : The correct choice is the third option.
The term young refers to the early stage of life, or the opposite of old age. In this context, the opposite of "young" is mature, as maturity generally implies full development or the state of being
Question : ______ administration became the model of the great emperor Akbar when he consolidated the Mughal Empire.
Option 1: Sher Shah Suri’s
Option 2: Alauddin Khilji’s
Option 3: Muhammad Tughluq’s
Option 4: Genghis Khan’s
Correct Answer: Sher Shah Suri’s
Solution : The correct option is Sher Shah Suri’s.
The administration of Sher Shah Suri became the model followed by the great emperor Akbar when he consolidated the Mughal Empire. Sher Shah Suri was a Pashtun Afghan who ruled North India from 1540 to 1545.
Question : The line chart given below shows the GDP of two countries P and Q in different five years.
L1 = The total GDP of country P in all 5 years. L2 = The total GDP of country Q in all 5 years. What is the value of (L2 – L1)?
Option 1: 180
Option 2: 240
Option 3: 280
Option 4: 160
Correct Answer: 240
Solution : L1 = The total GDP of country P in all 5 years. ⇒ L1 = 225 + 250 + 200 + 125 + 100 = 900 L2 = The total GDP of country Q in all 5 years. ⇒ L2 =
Question : How many numbers are there between 1 and 200 which are divisible by 3 but not by 7?
Option 1: 38
Option 2: 45
Option 3: 57
Option 4: 66
Correct Answer: 57
Solution : The numbers from 1 to 200 which are multiple of 3 are 3,6,9,...,198. The total number of multiples of 3 = $\frac{198 - 3 }{3}$ + 1 = 66 LCM of 3 and 7 is 21. The numbers from 1 to 200 which are multiples
Question : The given expression is equal to: $1-\frac{\tan ^2 \phi}{\sec ^2 \phi}$
Option 1: $\operatorname{sin}^2 \phi\cos ^2 \phi$
Option 2: $\operatorname{sin}^2 \phi\cot ^2 \phi$
Option 3: $\cot^2 \phi \cos^2 \phi$
Option 4: $\tan^2 \phi\cos^2 \phi$
Correct Answer: $\operatorname{sin}^2 \phi\cot ^2 \phi$
Solution : We know, $\sec^2 \phi-\tan^2 \phi$ = 1 and $\frac{\cos^2 \phi}{\sin^2 \phi}$ = $\cot^2 \phi$ So, $1-\frac{\tan^2 \phi}{\sec^2 \phi} $ = $\frac{\sec^2 \phi-\tan^2 \phi}{\sec^2 \phi}$ = $\frac{1}{\sec^2 \emptyset}$ = $\cos^2 \phi$ = $\frac{\sin^2 \phi\times{\cos^2 \phi}}{\sin^2 \phi}$ = $\sin^2 \phi\cot^2 \phi$ Hence, the correct
