Question 1
1 / -0

Seven employees - M, N, O, P, Q, R and S - reach office in a particular sequence. R reaches immediately after O. S reaches immediately before Q. Only two employees reach before M. No employee reaches before N. Only five employees reach before S.

Who ranks fifth in the sequence of reaching office?

M

B
N

C
R

D
O

Solution

The sequence obtained is:
Only two employees reach before M. No employee reaches before N. Only five employees reach before S.

N

Directions: Read the following information and answer the question given below.

In a certain language,
'oka peru' means 'fine cloth'
'meta lisa' means 'clear water'
'dona lisa peru' means 'fine clear weather'

Which code word in that language does mean 'weather'?

A
peru

B
oka

C
meta

D
dona

Solution

In the first and the third statements, the common code word is 'peru' and the common word is 'fine'.
So, 'peru' means 'fine'.
In the second and the third statements, the common code word is 'lisa' and the common word is 'clear'.
So, 'lisa' means 'clear'.
Thus, in the third statement, 'lisa' means 'clear' and 'peru' means 'fine'. So, 'dona' means 'weather'.

Question 8
1 / -0

Directions: Read the following information and answer the following question.

In a group of 7 friends namely Finn, Sheena, Roy, Jacob, Kyla, Tyler and Iqra having different weights, Sheena is heavier than Finn. Finn is heavier than Iqra but lighter than only Sheena. Jacob is heavier than Kyla and Roy only. Kyla is not the lightest. Iqra is heavier than Tyler.

Who is the second heaviest?

A
Sheena

B
Roy

C
Tyler

D
Finn

Solution

Sheena is heavier than Finn. Finn is heavier than Iqra but lighter than only Sheena.
Sheena > Finn > Iqra.
Jacob is heavier than Kyla and Roy only. Kyla is not the lightest.
Jacob > Kyla > Roy.
Iqra is heavier than Tyler.
Iqra > Tyler
By combining all conclusions, we get
Sheena > Finn > Iqra > Tyler > Jacob > Kyla > Roy
Finn is the second heaviest.
Question 9
1 / -0

How many pairs of letters are there in the word REGIMENTATION, each of which has as many letters between them as they have between them in the English alphabet?

A
1

B
2

C
3

D
4

Solution

The pairs are EO, ON and AG.
In the above table, if in any column, the extreme letter repeats in any row, then that letter forms a pair with the first letter of the row.
If the repeated letter is above the given word (here REGIMENTATION), then the first letter is the rightmost one and vice versa.

Example: Here, the letter G occurs between the 2 extreme letters G, hence, AG is one pair. The letter O repeats between the 2 extreme letters O, hence, NO forms another pair.
If the repeated letter is below the given word (here REGIMENTATION), then the first letter is the leftmost one and vice versa.
Example: Here, the letter O occurs between the 2 extreme letters O, hence, EO is one pair.

Directions For Questions

Directions: In the following question, two rows are given and to find out the resultant of a particular row, you need to follow the rules given below. Give answer according to the question asked.

Rules:
(1) If a two-digit odd number is followed by a two-digit odd number, they are to be added.
(2) If a two-digit even number is followed by a two-digit odd number, which is a perfect square, the even number is to be subtracted from the odd number.
(3) If a three-digit number is followed by a two-digit number, the first number is to be divided by the second number.
(4) If a prime number is followed by an even number, the two are to be added.
(5) If an even number is followed by another even number, the two are to be multiplied.

Find the sum of the resultants of the two rows.

47 21 16

552 69 26

A
1081

B
1296

C
1088

D
1126

Solution

First row:
The first number in the first row is 47 (odd) and it is followed by 21 (odd).
Using rule 1:
47 + 21 = 68 (resultant number - even)
Now, the first number is 68 (even) and the second number is 16 (even).
Using rule 5:
68 × 16 = 1088
So, resultant of the first row = 1088

Second row:
The first number is 552 (a three-digit number) and the second number is 69.
Using rule 3:
552/69 = 8
Now, the first number is 8 (even) and the second number is 26 (even).
Using rule 5:
8 × 26 =208
So, resultant of second row is 208

Therefore, sum of the resultants of the two rows = 1088 + 208 = 1296

Question 13
1 / -0

Directions: In the following question, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern in the given series.

2, 7, 24, 77, ___

A
238

B
138

C
338

D
438

Solution

The sequence is (Number × 3) + 1, 3, 5, 7, etc.
2 × 3 + 1 = 6 + 1 = 7
7 × 3 + 3 = 21 + 3 = 24
24 × 3 + 5 = 72 + 5 = 77
The missing number is (77 × 3) + 7 = 231 + 7 = 238
