Test: General Intelligence & Reasoning - 3 - Mechanical Engineering MCQ

In this question, the odd alphabets are chosen, i.e. MANISHA ⇒ 1^st 3^rd 5^th 7^th = MNSA, therefore RAVINA will give us RVN.

The analogy is addition of 3 characters to each of the alphabets.

Q + 3 = T,

S + 3 = V,

U + 3 = X,

W + 3 = Z

Similarly,

A + 3 = D,

C + 3 = F,

E + 3 = H,

G + 3 = J

Thus, ACEG will become DFHJ

In 14 : 30 ⇒ 14 : (14 + 1) × 2.

Similarly,

In 16 : ? ⇒ 16: (16 + 1) × 2 ⇒ 16 : 34

Hence, 34 is correct answer.

There is difference of 1 between each digit of 111 and 222.

Similarly, there will be difference of 1 between each digit of 444 and 333.

Hence, 333 is correct option.

Pesticide is used to protect plants from harmful insects similarly vaccinations is given to the baby to protect the baby from harmful diseases.

Hence Vaccination is related to Baby.

The pattern followed is that the number is the sum of the position of each letter in Englishalphabetical series i.e. In ABE ⇒ A → 1; B → 2; E → 5 & 1 + 2 + 5 = 8

Similarly, In KLO ⇒ K → 11; L → 12; O → 15 & 11 + 12 + 15 = 38

Thus 38 is the answer.

In 453 : 99

⇒ 453 = 4 + 5 + 3 = 12;

12 + 12/2 = 12 + 6 = 18

⇒ 99 = 9 + 9 = 18

Similarly,

⇒ 642 = 6 + 4 + 2 = 12

⇒ 12 + 12/2 = 12 + 6 = 18

1) 765 ⇒ 7 + 6 + 4 = 17

2) 346 ⇒ 6 + 4 + 3 = 13

3) 867 ⇒ 8 + 6 + 7 = 21

4) 396 ⇒ 3 + 9 + 6 = 18

Hence, 396 will be correct option.

White and Green are types of colors, similarly, Grapes are related to apples because both come under fruits.

Here, the 1st word contains the 2nd word i.e.

Garden : Plants → Garden contains Plants.

Similarly, Book contains Pages.

Thus, Pages is the correct alternative.

As the Crimes are solved in Court, in similar way Diseases are solved in Hospitals

Here,

2 + 1 = 3

3 + 2 = 5

5 + 4 = 9

9 + 8 = 17

17 + 16 = 33

Therefore 33 will complete the series.

Here 64 is perfect square but other three are not.

Hence, “64” is odd one among given alternatives.

Here, all the members except “Student” belong to the category of faculty.

Therefore, “Student” is the answer.

Grinding Maize, Barley and wheat we can get flour while we obtain oil from mustard seeds.

Trousers are worn below the waist whereas all the others are worn above the waist.

In all the words the second letter is 4^th to the right of first letter except in ‘MO’ where ‘O’ is 2^nd letter from ‘M’.

A + 4 = E;

C + 4 = G;

J + 4 = N;

M + 2 = O

The pattern is as follows,

F + 3 = I, I + 2 = K

P + 3 = S, S + 2 = U

T + 3 = W, W + 2 = Y

D + 3 = G, G + 3 = J

Thus, DGJ is the odd word.

All other sets contains alternate letters except MNO which is continuous series.

1) 243 - 132 = 111  (divisible by 3)

2) 183 - 54 = 129    (divisible by 3)

3) 108 - 97 = 11       (not divisible by 3)

4) 99 - 63 = 36       (divisible by 3)

Hence, 108 - 97 is odd one out. 

1) 369 ⇒ 3 + 6 = 9

2) 257 ⇒ 2 + 5 = 7

3) 346 ⇒ 3 + 4 = 7

4) 628 ⇒ 6 + 2 = 8

→ Except 346, last digit of number can be obtained by adding first and second digit of number.

This is Fibonacci series in which each term is obtained by adding previous two terms. Therefore, the required number is 8 + 5 = 13.

12 = 6 × 2

24 = 6 × 4

36 = 6 × 6

40 = not a multiple of 6

48 = 6 × 8

Hence 40 is the wrong term.

Given series is as follows

⇒ 3 × 1 = 3

⇒ 3 × 2 = 6

⇒ 6 × 3 = 18

⇒ 18 × 4 = 72

⇒ 72 × 5 = 360

Similarly,

⇒ 360 × 6 = 2160

Here We need to observe the position of 'x'. 'Vertex' has letter 'x' at the sixth position, 'Affix' has it at fifth, 'Unix' at fourth, Waxy at third and 'extra' at second.

Hence answer should be the word wherein 'x' is at the first position.

Hence Option 2 is the correct answer. 

Hexagon is a 6-sided figure

Heptagon is a 7-sided figure

Octagon is a 8-sided figure

Nonagon is a 9-sided figure

Decagon is a 10-sided figure

Given H = 8 which means H is 8^th letter in alphabet series.

Similarly,

HAT = 29 → H + A + T = 8 + 1 + 20 = 29

So the code number for BOX will be,

B + O + X = 2 + 15 + 24 = 41
