Test: General Intelligence & Reasoning - 1 - Mechanical Engineering MCQ

As scissors is used for cutting the clothes,

Similarly,

Axe is used for cutting wood.

Hence, the correct answer is wood.

Fan contains blades as its major component. Similarly, Book contains chapters as its major component.

Hence, Book : Chapter is the correct ans.

Elated means happy which is the opposite of despondent that means discourage. Similarly, enlightened is the opposite of ignorant.

The difference between the first two digits gives the second number.

For example, 7 – 6 = 1.

Similarly, 4 – 2 = 2.

Therefore, the final pairing will be 76 : 01 ∷ 42 : 2.

In 35 : 48

7 × 5 = 35

8 × 6 = 48

Similarly;

11 × 10 = 110

12 × 11 = 132

Hence, 132 is correct option.

In 36 : 25

⇒ 6² : 5²

⇒ 6² : (6 – 1)²

Similarly,

⇒ 100 : ?

⇒ 10² : (10 – 1)²

⇒ 10² : 9²

⇒ 100 : 81

Hence, “81” is required number.

Square, Rectangle and Circle are 2-dimensional figures while Sphere is a 3-dimensional figure.

Ear, Eye and Nose are the sensory organs but neck is not.

Hence Neck is different from other responses.

Just as Rabbit is an animals, Pentagon is a Figure.

Hence, answer is Pentagon: Figure.

OP, IJ, DE are consecutive letter in sequence but VU are consecutive letter but not in sequence.

Therefore, VU is odd one out.

ABCD is continuous series while in other series there are having some missing letters in between.

M + 1 = N, D + 1 = E

H + 1 = I, X + 1 = Y

L + 1 = M, V + 1 = W

R – 1 = Q, C – 1 = B

The odd one out is RQCB.

Here, 976, 778 and 895 are consecutive number whereas 997 is a prime number.

Therefore, “997” is odd one among given alternatives.

The digits of the given pairs of numbers are in reverse order of each other.

Hence odd should be 96-19 because instead of 19 it should be 69.

Here the pattern is : Number - Number × 2.

36 ­ 72 → 36 - 36 × 2 = 72

17 ­ 34 → 17 - 17 × 2 = 34

28 ­ 49 → 28 - 28 × 2 = 56

24 ­ 48 → 24 - 24 × 2 = 48

Thus 28 - 49, is the odd one out.

The pattern here is the letter ‘X’ which is to the immediate right of letter ‘Y’ is converted to ‘Y’ in every step and hence increasing the number of letter ‘Y’ in every step i.e.

YXXXXXX, YYXXXXX, YYYXXXX, YYYYXXX, YYYYYXX, YYYYYYX.

Hence, YYYYYYX is the correct alternative.

P – 1 = O, O – 1 = N, N- 1 – M, M- 1 = L

O – 2 = M, M- 2 = K, K – 2 = I, I – 2 = G

T – 1 = S, S- 1 = R, R- 1 = Q, Q – 1= P

Hence LGP is the correct answer.

The relation between the numbers is as follows,

18 - 4 = 14

14 - 4 = 10

10 - 4 = 6

Hence, the next number is 6 - 4 = 2.

The pattern followed is: (+ 2.5) is added in each number.

→ -4 + 2.5 = -1.5

→ -1.5 + 2.5 = 1

→ 1 + 2.5 = 3.5

→ 3.5 + 2.5 = 6

→ 6 + 2.5 = 8.5

→ 8.5

Hence, the missing number is 8.5 in the given series.

7

7 x 1= 7

7 x 2 x 1= 14

7 x 3 x 2 x 1 = 42

7 x 4 x 3 x 2 x 1 = 168

7 x 5 x 4 x 3 x 2 x 1 = 840

Hence missing number is 168.

ANTIQUES is coded as DQWLTXHV

⇒ A + 3 = D

⇒ N + 3 = Q

⇒ T + 3 = W

⇒ I + 3 = L

⇒ Q + 3 = T

⇒ U + 3 = X

⇒ E + 3 = H

⇒ S + 3 = V

Similarly,

⇒ F + 3 = I

⇒ O + 3 = R

⇒ X + 3 = A

Hence, in this language “FOX” will be coded as “ IRA”. 

Shyama, a woman, says that father of Rajiv’s father is my father.

Now, father of Rajiv’s father is Rajiv’s grandfather.

That means Shyama’s father is Rajiv’s grandfather.

Thus Syama is Rajiv’s aunt.
