Accepted Answer

Prithviraja III, popularly known as Prithviraj Chauhan, was the most famous ruler of the Chahamana dynasty. He ruled over Ajmer and Delhi and fought the Battles of Tarain.

Question 3

If 4 x 9 x 3 = 4 and 5 x 3 x 1 = 3, then 9 x 9 x 7 = ? 9 x 9 x 7 = ?

Accepted Answer

The pattern is the square root of the sum of the numbers. 4+9+3=16, √16=4. 5+3+1=9, √9=3. So, 9+9+7=25, and √25=5.

Question 4

The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. We drank a little and flung X-soon were all asleep Y-sand, thoroughly tired out, and Z-ourselves down on the

Accepted Answer

The sentence starts with 'We drank a little and flung'. 'ourselves down on the' (Z) logically follows 'flung'. Then 'sand, thoroughly tired out, and' (Y) describes the location and state. Finally, 'soon were all asleep' (X) concludes the action.

Question 5

If 27 (15) 33 and 41 (13) 53, then what is the value of 'A' in 26 (A) 35?

Accepted Answer

The middle number is the sum of the digits of the outer numbers. (2+7) + (3+3) = 15. (4+1) + (5+3) = 13. Thus, (2+6) + (3+5) = 16.

Question 6

If 5x = 30-y = 6z, then what is the value of (xy + yz + zx)/xyz?

Accepted Answer

Let $5^x = 30^{-y} = 6^z = k$. Then $5 = k^{1/x}$, $6 = k^{1/z}$, and $30 = k^{-1/y}$. Since $5 	imes 6 = 30$, $1/x + 1/z = -1/y$, which simplifies to $(xy+yz+zx)/xyz = 0$.

Question 7

In the following question, select the related word from the given alternatives. Kilometre : Metre : : Tonne : ?

Accepted Answer

A kilometre is a larger unit of length consisting of 1000 metres. Similarly, a tonne is a larger unit of mass consisting of 1000 kilograms.

Question 8

Share of E is equal to the combined shares of

Accepted Answer

Based on the provided data chart, the numerical value of E's share exactly matches the sum of the individual shares of F, A, and B combined.

Question 9

Two circles of same radius intersect each other at P and Q. If the length of the common chord is 30 cm and distance between the centres of the two circles is 40 cm, then what is the radius (in cm) of the circles?

Accepted Answer

The line joining the centres perpendicularly bisects the common chord. Thus, it forms a right triangle with legs 15 cm (half of 30) and 20 cm (half of 40). Radius = √(15² + 20²) = 25 cm.

Question 10

The areas of two similar triangles ΔABC and ΔPQR are 121 sq cms and 64 sq cms respectively. If PQ = 12 cm, what is the length (in cm) of AB?

Accepted Answer

The ratio of areas of similar triangles equals the square of the ratio of their corresponding sides. So, 121/64 = (AB/12)². Taking the square root gives 11/8 = AB/12, meaning AB = 16.5 cm.

Question 11

Select the related word from the given alternatives. Spring : Spiral :: Bangle : ?

Accepted Answer

A spring has a spiral shape. Following the exact same logic, a bangle has the shape of a circle. Therefore, 'Circle' is the correct answer.

Question 12

What is the name of the acid in an ant's sting?

Accepted Answer

An ant's sting contains formic acid (also known as methanoic acid), which causes the burning sensation. Acetic acid is found in vinegar, citric in citrus fruits, and lactic in curd.

Question 13

If 9@3=12; 15@4=22; 16@14=4; then what is the value of 6@2=?

Accepted Answer

The pattern is (A - B) × 2. For 9@3, (9-3)×2 = 12. Similarly, for 6@2, (6-2)×2 = 4×2 = 8.

Question 14

Which of the following device is used to measure humidity?

Accepted Answer

A hygrometer is a scientific instrument specifically designed to measure the amount of water vapor or humidity in the air. Meanwhile, a hydrometer measures the specific gravity of liquids.

Question 15

Select the related number from the given alternatives. 0.02 : 0.002 :: 1/3 : ? 0.02 : 0.002 :: 1/3 : ?

Accepted Answer

The pattern is dividing the first number by 10 to get the second. 0.02 / 10 = 0.002. Similarly, dividing 1/3 by 10 gives 1/30.

Question 16

In the following question, select the related number from the given alternatives. ACOUSTIC : 91 : : RENOUNCE : ? ACOUSTIC : 91 : : RENOUNCE : ?

Accepted Answer

The number represents the sum of the alphabetical positions of the letters. For RENOUNCE: R(18) + E(5) + N(14) + O(15) + U(21) + N(14) + C(3) + E(5) = 95.

Question 17

Δ ABC is right angled at B. If m∠A = 60°, then what is the value of 2 Sec C x 1/2 Sin A?

Accepted Answer

Since ∠B = 90° and ∠A = 60°, ∠C = 30°. The expression becomes 2 sec(30°) × 1/2 sin(60°) = 2(2/√3) × 1/2(√3/2) = 1.

Question 18

What will be the net discount (in %) of two successive discounts of 15% and 35%?

Accepted Answer

Use the successive discount formula: x + y - (xy/100). Here, 15 + 35 - (15 × 35)/100 = 50 - 5.25 = 44.75%.

Question 19

What is the sum of the first 12 terms of an arithmetic progression if the 3rd term is -13 and the 6th term is -4? 9/7/2017 Staff Selection Commision http://thepracticetest.in/cs_cglet1_17/response_questions.php?t_id=MTgwODIwMTc=&appid=1368062d74107fc05177712c90c3885c# 16/22

Accepted Answer

Given a+2d=-13 and a+5d=-4. Solving these gives d=3 and a=-19. The sum of the first 12 terms is 6[2(-19) + 11(3)] = 6[-38+33] = -30.

Question 20

Select the odd word from the given alternatives. SSC CGL 2017 TIER I AUGUST 20, 2017 SHIFT 2 QUESTION PAPER
