If ‘P’ stands for ‘×’, ‘Q’ stands for ‘÷’, ‘R’ stands for ‘−’ and ‘S’ stands for ‘+’, what will come in place of the question mark ‘?’ in the following equation?
78 Q 3 S (55 Q 5) P 4 R 16 P 5 S 65 = ?
55

35
Correct answer
55
Why this answer is correct
The logic followed here is,
BODMAS Table:
| P | Q | R | S |
|---|---|---|---|
| × | ÷ | − | + |
Given expression: 78 Q 3 S (55 Q 5) P 4 R 16 P 5 S 65
After replacing the letters with their respective signs and following the BODMAS rule,
= 78 ÷ 3 + (55 ÷ 5) × 4 − 16 × 5 + 65
= 78 ÷ 3 + 11 × 4 − 16 × 5 + 65
= 26 + 11 × 4 − 16 × 5 + 65
= 26 + 44 + 65 − 80
= 135 − 80
= 55
Hence, the correct answer is "option 1"
Town X is to the south of Town Y. Town Z is to the west of Town X. Town P is to the north of Town Z. Town Q is to the east of Town P. Town Y is to the north-west of Town Q. What is the position of Town X with respect to Town Q?
South-west
South-east
North-west
North-east
Correct answer
South-west
Why this answer is correct
Given:
The Final Diagram ,
Town X is South - West respect to Town Q
Hence, the correct answer is "option 1"
What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
43 – 85 × 5 + 10 ÷ 3 = ?
38
32
30
35
Correct answer
30
Why this answer is correct
BODMAS Table:
Sign Interchange:
| Original Sign | New Sign |
|---|---|
| + | − |
| × (times) | ÷ (div) |
**Given Equation:**43 − 85 × 5 + 10 ÷ 3 = ?
After interchanging the signs, and follows BODMAS rule
= 43 + 85 ÷ 5 − 10 × 3
= 43 + 17 − 10 × 3
= 43 + 17 − 30
= 60 − 30
= 30
Hence, the correct answer is "option 3"
In a certain code language,
A # B means ‘A is the daughter of B’,
A @ B means ‘A is the brother of B’,
A ! B means ‘A is the wife of B’ and
A & B means ‘A is the father of B’.
How is N related to V if ‘N @ K # S & R ! V’?
Wife's father
Wife's brother
Husband
Son
Correct answer
Wife's brother
Why this answer is correct
BODMAS Table:
Let us first decode the given symbols and then draw a family tree.
| Symbol | # | @ | ! | & |
|---|---|---|---|---|
| Meaning | Daughter | Brother | Wife | Father |
Given : N @ K # S & R ! V
Therefore, N is the brother of R, who is the wife of V . N is the Wife's brother of V.
Hence, the correct answer is "Option 2".
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/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
91, 184
88, 178
99, 200
92, 184
76, 152
104, 218
Correct answer
99, 200
Why this answer is correct
The logic followed here is:
Logic: Second Number = (First Number × 2) + 2
For the first set (91, 184)
⇒ (91 × 2) + 2
⇒ 182 + 2 = 184.
For the second set (88, 178)
⇒ (88 × 2) + 2
⇒ 176 + 2 = 178.
Applying the same logic to the options:
For Option 1: (99, 200)
⇒ (99 × 2) + 2
⇒ 198 + 2 = 200.
Hence, the correct answer is 'Option 1'.
Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements: Some stones are minerals. All minerals are elements.
Conclusions
(I) Some elements are stones.
(II) All stones are minerals.
Both conclusions (I) and (II) follow
Only conclusion (I) follows
Neither conclusion (I) nor (II) follows
Only conclusion (II) follows
Correct answer
Only conclusion (I) follows
Why this answer is correct
Statements:
Some stones are minerals.
All minerals are elements.
Conclusions:
(I) Some elements are stones.
(II) All stones are minerals.
The least possible Venn diagram for the given statements is:
(I) Some elements are stones — True
Since all minerals are elements and some stones are minerals, the shared region between stones and minerals must reside within the elements set.
(II) All stones are minerals — False
The statement only establishes that a portion of stones is minerals; there is no requirement for the entire set of stones to be contained within minerals.
Only conclusion (I) follows
What should come in place of the ‘?’ in the given series?
19 36 59 94 147 ?
226
228
220
224
Correct answer
224
Why this answer is correct
The logic followed here is:
19 + 17 = 36
36 + 23 = 59
59 + 35 = 94
94 + 53 = 147
147 + 77 = 224
Thus, the missing term in the series is 224.
Hence, the correct answer is 'Option 4';
In a row of 35 people facing the north, Geeta is 15th from the right end. If Nalini sits 14th to the left of Geeta, what is Nalini’s position from the left end of the row?
4th
9th
7th
5th
Correct answer
7th
Why this answer is correct
The logic followed here is,
Total number of people in the row = 35
Position of Geeta from the right end = 15th
Nalini sits 14th to the left of Geeta.
Position of Nalini from the right end = Position of Geeta from the right end + 14
= 15 + 14
= 29th from the right end
Position from the left end = (Total number of people − Position from the right end) + 1
= (35 − 29) + 1
= 6 + 1
= 7th
Hence, the correct answer is "option 3"
What should come in place of ‘?’ in the given series?
28 33 44 61 84 113 ?
140
148
137
143
Correct answer
148
Why this answer is correct
The logic followed here is:
The sequence of first differences is 5, 11, 17, 23, 29, 35.
The second difference is a constant 6.
Therefore, the missing term is 113 + 35 = 148.
Hence, the correct answer is 'Option 2';
