Question : Directions: Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: I. All chains are circles. II. No chain is square. Conclusions: I. Some circles are square. II. Some circles are chains.
Option 1: Neither conclusion I nor II follows
Option 2: Only conclusion II follows
Option 3: Both conclusions I and II follow
Option 4: Only conclusion I follows
Correct Answer: Only conclusion II follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some circles are square – It is a possibility that the circles representing circles and squares overlap. But this is not definite.
Question : Directions: A man walks from a point towards the south. He turns right at the right angle, then turns right again at the right angle. In what direction is he walking now?
Option 1: West
Option 2: North
Option 3: South

Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 46, 36, 28, 22, 18, ?
Option 1: 16
Option 2: 14
Option 3: 15
Option 4: 13
Correct Answer: 16
Solution : Given: 46, 36, 28, 22, 18, ?
Subtract consecutive even numbers in the decreasing order to complete the series. 46 – 10 = 36; 36 – 8 = 28; 28 – 6 = 22; 22 – 4 = 18; 18 – 2 = 16
So,
Question : What will be the area of a rectangular field of length 45 cm and breadth 32 cm?
Option 1: $1340\ \text{cm}^2$
Option 2: $145\ \text{cm}^2$
Option 3: $1440\ \text{cm}^2$
Option 4: $1120\ \text{cm}^2$

Question : The simple interest on a sum for 5 years is Rs. 7,590. The rate of interest for the first 3 years is 6 percent per annum and for the next 2 years is 14 percent per annum. What is the sum?
Option 1: Rs. 17,000
Option 2: Rs. 15,000
Option 3: Rs. 14,000
Option 4: Rs. 16,500
Correct Answer: Rs. 16,500
Solution : Given: The simple interest on a sum for 5 years is Rs. 7,590. Let the principal be Rs. $P$. We know, Simple interest = $\frac{\text{Principal × Time × Rate}}{100}$ The simple interest for the first 3 years at a 6% rate = $\frac{P\times 3\times
Question : From which language has the term 'democracy' been derived?

Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. 339 : 1022 :: 58 : 179 :: 25 : ?
Option 1: 80
Option 2: 70
Option 3: 75
Option 4: 125
Correct Answer: 80
Solution : Given: 339 : 1022 :: 58 : 179 :: 25 : ?
Like, 339 : 1022→(339 × 3) + 5 = 1017 + 5 = 1022 58 : 179→(58 × 3) + 5 = 174 + 5 = 179 Similarly, follow the same pattern for
Question : Directions: If MUSTARD is written as 132119201184, how is PROFUSE written in that code?
Option 1: 16815621195
Option 2: 16181562195
Option 3: 16181521195
Option 4: 161815621195
Correct Answer: 161815621195
Solution : Given: MUSTARD ⇒ 132119201184 PROFUSE ⇒ ?

Question : The value of $\sqrt{3\sqrt{3\sqrt{3......}}}$ is equal to:
Option 1: $\sqrt{3}$
Option 2: $3$
Option 3: $2\sqrt{3}$
Option 4: $3\sqrt{3}$
Correct Answer: $3$
Solution : Given: $\sqrt{3\sqrt{3\sqrt{3......}}}$ Let $x = \sqrt{3\sqrt{3\sqrt{3......}}}$ $ ⇒ x = \sqrt{3x}$ By squaring both sides, we get: $ ⇒ x^{2} = 3x$ $ ⇒ x = 3$ Hence, the correct answer is $3$.
