SSC CGL Tier 1 Mock Test - 7 - Question 1

Direction: In the given question, in three out four figures, figure (i) is related to figure (ii) in same particular manner. Spell out the pair in which relationship does not exist between figure (i) and figure (ii).

Detailed Solution for SSC CGL Tier 1 Mock Test - 7 - Question 1

In each pair of Figures (i) and (ii), the relationship is such that figure (i) is rotated 90° clockwise to form figure (ii). In option (B) when figure (i) is rotated 90° clockwise, it does not form figure (ii).

So option figure (ii) is the odd one.

SSC CGL Tier 1 Mock Test - 7 - Question 2

Select the missing number from the given series.

81, 41.5, 42.5, 64.75, 130.5, ?, 982.75

Detailed Solution for SSC CGL Tier 1 Mock Test - 7 - Question 2

The logic is as:

81 × 0.5 + 1 = 41.5

41.5 × 1 + 1 = 42.5

42.5 × 1.5 + 1 = 64.75

64.75 × 2 + 1 = 130.50

130.50 × 2.5 + 1 = 327.25

327.25 × 3 + 1 = 982.75

So, the missing term is 327.25.

SSC CGL Tier 1 Mock Test - 7 - Question 8

Select the number which can be placed at the sign of the question mark (?) from the given alternatives.

Detailed Solution for SSC CGL Tier 1 Mock Test - 7 - Question 8

The logic is:

02 + 1 = 0 + 1 = 1

12 + 1 = 1 + 1 = 2

22 + 1 = 4 + 1 = 5

32 + 1 = 9 + 1 = 10

42 + 1 = 16 + 1 = 17

52 + 1 = 25 + 1 = 26

62 + 1 = 36 + 1 = 37

72 + 1 = 49 + 1 = 50

So, ‘50’ is the correct answer.

SSC CGL Tier 1 Mock Test - 7 - Question 9

Five people – A, B, C, D, and E are sitting in a line facing South, not necessarily in the same order. E is sitting at one of the ends. A is sitting in the exact middle. Neither C nor D sit at any of the ends. C sits on the immediate left of B. Who sits second to the right of A?

Detailed Solution for SSC CGL Tier 1 Mock Test - 7 - Question 9

According to the question, 

E is sitting at one of the ends.

Case 1

Case 2

A is sitting in the exact middle.

Neither C nor D sit at any of the ends.

(Therefore, B sits at one of the ends)

Case 1

Case 2

C sits on the immediate left of B.

(Here case 1 gets eliminated because in this case, there is no one sitting on the left of B. Also, since the only D is left, so D sits Between A and E)

This is the final arrangement.

Thus, B sits second to the right A.

SSC CGL Tier 1 Mock Test - 7 - Question 10

Direction: If 'Z' denotes 'addition', 'X' denotes 'multiplication', 'Y' denotes 'division', and 'W' denotes 'subtraction', then what will be the value of the following expression?

15 Y (11 Z 4) Z 3 X 4 (19 Z 3) Y 11 X 3 (3 Z 2)

Detailed Solution for SSC CGL Tier 1 Mock Test - 7 - Question 10

Decoding the information:

Given:

15 Y (11 Z 4) Z 3 X 4 (19 Z 3) Y 11 X 3 (3 Z 2)

After replacing the signs from left to right and using the BODMAS rule,

= 15 ÷ (11 + 4) + 3 × 4 (19 + 3) ÷ 11 × 3 (3 + 2)

= 15 ÷ 15 + 3 × 4 × 22 ÷ 11 × 3 × 5

= 1 + 3 × 4 × 2 × 3 × 5

= 1 + 3 × 4 × 2 × 15

= 1 + 3 × 4 × 30

= 1 + 360

= 361

So, “361” is the correct answer.

Then we get,

289 = 2 + 8 + 9 = 19 = 1 × 9 = 9

Therefore, the correct answer is 9.

A train can completely cross a 1000-metre long bridge in 15 seconds. It can completely cross another 1300-metre long bridge in 19 seconds. What is the length of the train?
Detailed Solution for SSC CGL Tier 1 Mock Test - 7 - Question 53

Given:

A train can completely cross a 1000-metre long bridge in 15 seconds.

It can completely cross another 1300-metre long bridge in 19 seconds.

Concept used:

Speed = Distance/Time

Calculation:

Let the length of the train be 'x'

According to the question,

(1000 + x)/15 = (1300 + x)/19

⇒ (1000 + x) × 19 = (1300 + x) × 15

⇒ 19000 + 19x = 19500 + 15x

⇒ 4x = 500

⇒ x = 500/4 = 125 m

∴ The length of the train is 125 m.
