Which two signs should be interchanged to make the given equation correct?
200 + 180 ÷ 12 × 9 - 55 = 120
× and -
Correct answer
Why this answer is correct
Let's check each option,
1) + and ÷
→ 200 ÷ 180 + 12 × 9 - 55 = 120
→ 10/9 + 12 × 9 - 55 = 120
→ 10/9 + 108 - 55 = 120
→ 982/9 - 55 ≠ 120
→ LHS ≠ RHS
2) + and -
→ 200 - 180 ÷ 12 × 9 + 55 = 120
→ 200 - 15 × 9 + 55 = 120
→ 200 - 135 + 55 = 120
→ 255 - 135 = 120
→ LHS = RHS ⇒ Satisfies the equation.
3) × and -
→ 200 + 180 ÷ 12 × 9 - 55 = 120
→ 200 + 15 × 9 - 55 = 120
→ 200 + 135 - 55 = 120
→ 335 - 55 = 120
→ 280 ≠ 120
→ LHS ≠ RHS
4) + and ×
→ 200 × 180 ÷ 12 + 9 - 55 = 120
→ 200 × 15 + 9 - 55 = 120
→ 3000 + 9 - 55 = 120
→ 3009 - 55 = 120
→ 2954 ≠ 120
→ LHS ≠ RHS
Here, we can see that only Option 2 satisfies the equation.
Hence, the correct answer is "+ and -".
Select the set in which the numbers are related in the same way as are the numbers of the given set. (
NOTE:
Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / substracting / 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.)
(4, 42, 17)
(6, 86, 37)
(8, 164, 65)
(9, 180, 82)
(5, 52, 26)
(7, 114, 50)
Correct answer
(7, 114, 50)
Why this answer is correct
The logic followed here is,
Logic: Second Number = (First Number + Third Number) × 2
(4, 42, 17)
→ 42 = (4 + 17) × 2
→ 42 = 21 × 2
(6, 86, 37)
→ 86 = (6 + 37) × 2
→ 86 = 43 × 2
Now, let's check each option,
1) (8, 164, 65)
→ 164 = (8 + 65) × 2
→ 164 ≠ 73 × 2
2) (9, 180, 82)
→ 180 = (9 + 82) × 2
→ 180 ≠ 91 × 2
3) (5, 52, 26)
→ 52 = (5 + 26) × 2
→ 52 ≠ 31 × 2
4) (7, 114, 50)
→ 114 = (7 + 50) × 2
→ 114 = 57 × 2 ⇒ Satisfies the logic.
Here, we can see that only Option 4 satisfies the logic.
Hence, the correct answer is "(7, 114, 50)".
Select the option that is related to the third word in the same way as the second word is related to the first word.
Cygnet : Swan :: Colt : ?
Bear
Horse
Stag
Sheep
Correct answer
Horse
Why this answer is correct
The logic followed here is,
Cygnet: Swan → A cygnet is a young swan.
Similarly,
Colt: ? → A colt is a young male horse.
Hence, the correct answer is "Horse".
Select the option that represents the correct order of the given words as they would appear in an English dictionary.
6, 4, 5, 1, 2, 3

6, 4, 2, 3, 5, 1
Correct answer
6, 4, 5, 1, 2, 3
Why this answer is correct
The correct arrangement as per the English dictionary is shown below,
6) Mecamylamine
4) Mechanical
5) Meclizine
1) Meconium
2) Medication
3) Mediocrity
Hence, the correct answer is "6, 4, 5, 1, 2, 3".

Ten people are sitting in two parallel rows containing 5 people each, in such a way that there is equal distance between adjacent persons.
In Row 1 – A, B, C, D and E are seated and all of them are facing the north.
In Row 2 – P, Q, R, S and T are seated and all of them are facing the south.
Thus, each person is facing another person from the other row.
Neither A nor D is sitting at any of the extreme ends of the row. A is sitting to the immediate right of D. P is facing the person who is sitting second to the right of D. Only two people are sitting between P and Q. C is sitting to the immediate right of E. B is facing the person who is sitting second to the right of R. S is sitting at one of the positions to the right of T.
Who is facing T?
E
C
A
B
Correct answer
C
Why this answer is correct
According to the given information,
1) Neither A nor D is sitting at any of the extreme ends of the row.
3) P is facing the person who is sitting second to the right of D.
4) Only two people are sitting between P and Q.
5) C is sitting to the immediate right of E.
6) B is facing the person who is sitting second to the right of R.
Here, we can see that C is facing T.
Hence, the correct answer is "C".
If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, what will come in place of the question mark (?) in the following equation?
27 B 7 D 39 A 3 C 47 = ?
223
220
222
221
Correct answer
223
Why this answer is correct
| Sign | A | B | C | D |
|---|---|---|---|---|
| Means | ÷ | × | + | - |
After replacing the signs, the equation we get:
→ 27 × 7 - 39 ÷ 3 + 47 =?
→ 27 × 7 - 13 + 47 =?
→ 189 - 13 + 47 =?
→ 236 - 13 =?
→ 223 =?
Hence, the correct answer is "223".
Three statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements :
No crow is a monkey.
All monkeys are turtles.
No turtle is a snail.
Conclusions :
I. Some snails being crows is a possibility.
II. No turtle is a crow.
Either conclusion I or II follows
Both conclusions I and Il follow
Neither conclusion I nor II follows
Only conclusion I follows
Correct answer
Only conclusion I follows
Why this answer is correct
The least possible venn diagram has been shown below,
Conclusions:
I. Some snails being crows is a possibility → Follows (Because it is not definite, but it is possible).
II. No turtle is a crow → Not Follows (Because it is not definite, but it is possible).
Hence, the correct answer is "Only conclusion I follows".
If A = B > C = D and F < E = D < A, then which of the following options is NOT correct?
F < C
D > F
C = E
A < D
Correct answer
A < D
Why this answer is correct
The given expressions are: A = B > C = D and F < E = D < A.
On combining the expressions, we get: A = B > C = D = E > F
Now, let's check each option,
1) F < C → True
2) D > F → True
3) C = E → True
4) A < D → False
Hence, the correct answer is "A < D".

Hence, the correct answer is "Option 4".
If '+' means, '÷', '-' means '+', '×' means '-', '÷' means '×', then what will come in place of the question mark (?) in the following equation?
14 - 3 ÷ 8 × 63 + 9 = ?
31
33
50
45
Correct answer
31
Why this answer is correct
| Sign | + | - | × | ÷ |
|---|---|---|---|---|
| Interchange with | ÷ | + | - | × |
The equation we get after interchanging the signs,
→ 14 + 3 × 8 - 63 ÷ 9 =?
→ 14 + 3 × 8 - 7 =?
→ 14 + 24 - 7 =?
→ 38 - 7 =?
→ 31 =?
Hence, the correct answer is "31".
In a certain code language, ‘BROADLY’ is written as ‘77’ and 'FRANTIC' is written as ‘71’. How will ‘CRUMBLE’ be written as in that language?
72
76
75
74
Correct answer
74
Why this answer is correct
The logic followed here is,
Logic: The words have been coded as the sum of the positional values of the letters.
BROADLY → (2 + 18 + 15 + 1 + 4 + 12 + 25) = 77
FRANTIC → (6 + 18 + 1 + 14 + 20 + 9 + 3) = 71
Similarly,
CRUMBLE → (3 + 18 + 21 + 13 + 2 + 12 + 5) = 74
Hence, the correct answer is "74".

What day of the week was on 28th January 2002?
Wednesday
Tuesday
Sunday
Monday
Correct answer
Monday
Why this answer is correct
Given date: 28 January 2002.
| Year | Odd Days |
|---|---|
| 100 | 5 odd days |
| 200 | 3 odd days |
| 300 | 1 odd day |
| 400 | 0 odd days |
Now,
Till 2002 → 2000 + 2
| Leap Year | 2 Odd days |
|---|---|
| Ordinary Year | 1 Odd day |
In 2000 Years the odd day is 0,
In 2 Years the odd day is 2,
And, from 1st Jan 2002 to 28 Jan 2002:
→ 27 days in January (since we are considering up to the 28th): 27 days.
Total odd days → 2 + 27 = 29 days = 29/ 7 = 4 weeks and 1 odd days.
→ 1 represents Monday.
So, 28 January 2002 is a Monday.
Hence, the correct answer is "Monday".
‘A + B' means 'A is the brother of B'
'A - B' means 'A is the mother of B'
'A × B' means 'A is the husband of B'
'A ÷ B' means 'A is the sister of B'
'A # B' means 'A is the daughter-in-law of B'
If 'C - M + S + K × R # T', then which of the following statements is not correct?
K and M are brothers.
T is the father of S.
S is the grandson of C.
R is the wife of M's brother.
Correct answer
S is the grandson of C.
Why this answer is correct
Given Symbols and their meanings:
| Symbol | + | - | × | ÷ | # |
|---|---|---|---|---|---|
| Meaning | Brother | Mother | Husband | Sister | Daughter-in-law |
Given expression: C - M + S + K × R # T
Decoding the expression step-by-step:
C - M means C is M's mother.
M + S means M is S's brother.
S + K means S is K's brother.
K × R means K is R's husband.
R # T means R is T's daughter-in-law.
Family Chart:
Now check all the options:
K and M are brothers. (Correct)
T is S's father. (Correct)
S is C's grandson. (Incorrect, as S is the son of C)
R is the wife of M's brother. (Correct)
Hence, the correct answer is "Option 3".
