Question 75

JSSC SI 2017• Logical Reasoning

Select the analogy which you think matches best in the given example.

6 : 252 :: 9 : ?

  1. AOption (a)

    720

  2. BOption (b)

    788

  3. COption (c)

    810

  4. DOption (d)

    854

View answer & explanation

Correct answer

Answer: (c)C.

810

Why this answer is correct

Given

6 : 252 :: 9 : ?

The logic here is

First number : Second number

Second number = (First number)³ + (First number)²

6 : 252

⇒ (6)³ + (6)²

⇒ 216 + 36

⇒ = 252

Similarly, 

9 : ?

⇒ (9)³ + (9)²

⇒ 729 + 81

⇒ = 810

Hence, "810" is the correct answer.

Question 76

JSSC SI 2017• Logical Reasoning

    118

  4. DOption (d)

    219

View answer & explanation

Correct answer

Answer: (b)B.

0

Why this answer is correct

Given equation is:

{17 × 12) – (4/2)} + (23 - 6)]/0

Decoding the given information:

SymbolStands for
+÷
-+
×-
/×

 

Substituting the operations in the equation:

[{(17 - 12) + (4 × 2)} ÷ (23 + 6)] × 0

BODMAS Rule:

Using the BODMAS Rule:

⇒ [{(5) + (4 × 2)} ÷ (23 + 6)] × 0

⇒ [{(5) + (8)} ÷ (23 + 6)] × 0

⇒ [{13} ÷ (23 + 6)] × 0

⇒ [{13} ÷ (29)] × 0

⇒ [0.448] × 0

⇒ = 0

Hence, the correct answer is "0".

Question 77

    1, 5, 3, 2, 4

View answer & explanation

Correct answer

Answer: (a)A.

3, 1, 5, 4, 2

Why this answer is correct

The logic follows here is :- 

From the given words They are area wise that we have to arrange it in Ascending order

Tirupati → Andhra Pradesh → India → World → Universe

So, logical and meaningful order is 3, 1, 5, 4, 2

Hence, the correct answer is "3, 1, 5, 4, 2".

Question 78

JSSC SI 2017• Logical Reasoning

If + means - , - means ×, × means ÷ and ÷ means + in the given equation, then [{(217 × 310) + ( 190 + 114)} × 190] – 100 ÷ 50 = ?

  1. AOption (a)

    40

  2. BOption (b)

  3. COption (c)

    80

  4. DOption (d)

    100

View answer & explanation

Correct answer

Answer: (b)B.

10.37

Why this answer is correct

Given equation is:

[{(217 × 310) + ( 190 + 114)} × 190] – 100 ÷ 50 = ?

Decoding the given information:

SymbolStands for
+-
-×
×÷
÷+

 

Substituting the operations in the equation:

[{(217 ÷ 310) - (190 - 114)} ÷ 190] × 100 + 50

BODMAS Rule:

Using the BODMAS Rule:

⇒ [{(0.7) - (190 - 114)} ÷ 190] × 100 + 50

⇒ [{(0.7) - (76)} ÷ 190] × 100 + 50

⇒ [-75.3 ÷ 190] × 100 + 50

⇒ -0.396 × 100 + 50

⇒ -39.63 + 50

⇒ = 10.37

Hence, the correct answer is "10.37".

In this statement, the genders of the T and S are not defined. So, this is not a sufficient statement to tell the father of P

  1. U is the mother of Q.

In this statement, it is clear that S is the father of P. So, this statement is sufficient to tell the father of P is S.

Hence, "only 2" is the answer.
