BODMAS Table:
Decoding the given information:
| Alphabet | + | − | × | ÷ |
|---|---|---|---|---|
| Meaning | − | × | ÷ | + |
Now, replacing the sign from left to right using BODMAS Rule, we get:
⇒ 97 × 11 + 67 − 864 ÷ 16 = ?
⇒ 1067 + 67 − 54 = ?
⇒ 1134 − 54 = ?
⇒ 1080
Hence, the correct option is "Option 4".

In a row of \( 42 \) people facing north, Kunal is \( 11^{th} \) from the left end. If Riya sits \( 5^{th} \) to the right of Kunal, what is Riya’s position from the right end of the line?
25th
26th
24th
27th
Correct answer
27th
Why this answer is correct
Given:
Kunal is 11th from the left end and Riya sits 5 places to the right of Kunal in a row of 42 people.
Here,
Riya’s position from the left end = 11 + 5 = 16th
Now, Riya’s position from the right end = 42 − 16 + 1 = 27th
So, Riya is 27th from the right end.
Hence, the correct answer is "Option 4".
Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(
NOTE:
Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
\( (13.3, 12.5, 11.8) \)
\( (45.6, 44.8, 44.1) \)
(71.7, 70.9, 70.1)
(39.4, 38.6, 37.8)
(69.5, 68.7, 68.6)
(27.9, 27.1, 26.4)
Correct answer
(27.9, 27.1, 26.4)
Why this answer is correct
The logic followed here is:
Logic:
Second Number = First Number + 0.8
Third Number = Second Number + 0.7.
For, (13.3, 12.5, 11.8) →
⇒ 13.3 − 12.5 = 0.8
⇒ 12.5 − 11.8 = 0.7
For, (45.6, 44.8, 44.1) →
⇒ 45.6 − 44.8 = 0.8
⇒ 44.8 − 44.1 = 0.7
Now, checking the options:
Option 1) (71.7, 70.9, 70.1)
⇒ 71.7 − 70.9 = 0.8
⇒ 70.9 − 70.1 = 0.8 ≠ 0.7
Option 2) (39.4, 38.6, 37.8)
⇒ 39.4 − 38.6 = 0.8
⇒ 38.6 − 37.8 = 0.8 ≠ 0.7
Option 3) (69.5, 68.7, 68.6)
⇒ 69.5 − 68.7 = 0.8
⇒ 68.7 − 68.6 = 0.1 ≠ 0.7
Option 4) (27.9, 27.1, 26.4)
⇒ 27.9 − 27.1 = 0.8
⇒ 27.1 − 26.4 = 0.7
Hence, the correct answer is Option 4.
Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group?

The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
NQ - JM
LO - HL
KN - GJ
HK - DG
Correct answer
LO - HL
Why this answer is correct
The logic followed here is:
Option 1) NQ – JM
Option 2) LO – HL
Option 3) KN – GJ
Option 4) HK – DG
Here, LO – HL is odd from the given options.
Hence, the correct answer is "Option 2".
In a certain code language,
‘A + B’ means ‘A is the son of B’,
‘A – B’ means ‘A is the mother of B’,
‘A × B’ means ‘A is the brother of B’ and
‘A ÷ B’ means ‘A is the father of B’.
How is M related to S if \( ‘M + N \div O \times P – S’ \)?
Daughter’s son
Mother’s brother
Brother’s son
Father’s brother
Correct answer
Mother’s brother
Why this answer is correct
Family Chart:
Decoding the Symbols:
| Symbol | + | − | × | ÷ |
|---|---|---|---|---|
| Meaning | Son | Mother | Brother | Father |
Given: M + N ÷ O × P − S
It means: M is the son of N, N is the father of O, O is the brother of P, and P is the mother of S.
Hence, M is also the mother’s brother of S.
Hence, the correct answer is "Option 2".

Correct answer
1
Why this answer is correct
Given: A, B, C, D, E, F and G are sitting in a straight line facing North.
No one sits to the right of B.
Only three people sit between B and G.
Only two people sit between G and D.
A sits third to the left of C.
F sits to the immediate right of C.
Now, People to the left of E = only A = 1
Hence, the correct answer is "Option 4".

Now,
Odd numbers, which are immediately preceded by an even number and also immediately followed by an even number.
So, Needed pattern is: Even Number - Odd Number - Even Number
(Left) 2 7 4 7 7 3 3 3 1 4 8 9 8 8 2 8 5 6 7 9 7 1 3 3 1 6 2 (Right)
So, total valid odd numbers = 3
