Why this answer is correct
The logic followed here is:
Hence, "Option 2" is the correct answer.
From the options given below, choose the correct option and write it in place of the question mark:
| 1 | 2 | 3 |
|---|---|---|
| 11 | 7 | 5 |
| 120 | 45 | ? |
19
15
17
16
Correct answer
16
Why this answer is correct
The logic followed here is:
| 1 |
|---|
| 11 |
| 120 |
→ 112 - 12 = 120
→ 121 - 1 = 120
→ 121 = 121 (LHS = RHS)
And,
| 2 |
|---|
| 7 |
| 45 |
→ 72 - 22 = 45
→ 49 - 4 = 45
→ 45 = 45 (LHS = RHS)
Similarly,
| 3 |
|---|
| 5 |
| ? |
→ 52 - 32 = ?
→ 25 - 9 = ?
→ 16 = ?
Hence, "Option 4" is the correct answer.
Suresh runs 1 km east of one place. After that he turns south and walks 5 km. After that, turns east and walks 2 km and then turns north and moves 9 km. Now how far has he reached from his initial place?
3 km
5 km
4 km
7 km
Correct answer
5 km
Why this answer is correct
Given:
Suresh runs 1 km east of one place.
After that he turns south and walks 5 km.
After that, turns east and walks 2 km and then turns north and moves 9 km.
By applying Pythagoras theorem :
(AB)2 = (AC)2 + (BC)2
(AB)2 = (4)2 + (3)2
(AB)2 = 16 + 9
AB = √25
AB = 5 km
Here, Suresh is 5 km far from his initial position.
Hence, "Option 2" is the correct answer.
If NOR = 2 – 3 – 6, then how will you write REST in this code language?
6 - 19 - 6 - 7
5 - 19 - 5 - 8
6 - 19 - 7 - 8
6 - 18 - 5 - 8
Correct answer
6 - 19 - 7 - 8
Why this answer is correct
The logic followed here is:
NOR = 2 – 3 – 6
Similarly,
REST = ?
Hence, the correct answer is "Option 3".
How many times do the digits '1', '3' and '7' appear together in the following series of numbers when '7' is in the middle and '7' has '1' on one side and '3' on the other side?
2 9 7 3 1 7 3 7 7 1 3 3 1 7 3 8 5 7 1 3 7 7 1 7 3 9 0 6
3
4
5
More than 5
Correct answer
3
Why this answer is correct
Given series: 2 9 7 3 1 7 3 7 7 1 3 3 1 7 3 8 5 7 1 3 7 7 1 7 3 9 0 6
According to the question:
Required condition: 1/3 - 7 - 1/3
2 9 7 3 1 7 3 7 7 1 3 3 1 7 3 8 5 7 1 3 7 7 1 7 3 9 0 6
Thus, three times do the digits '1', '3' and '7' appear together in the given series of numbers when '7' is in the middle and '7' has '1' on one side and '3' on the other side.
Hence, "Option 1" is the correct answer.
Ramesh's brother Suresh is 562 days older than him, while his sister Reena is 75 weeks older than Suresh. Now if Reena was born on Friday, on which day was Ramesh born?
Wednesday
Sunday
Monday
Thursday
Correct answer
Wednesday
Why this answer is correct
Given:
Reena (562 days + 75 weeks) > Suresh (562 days) > Ramesh
2) Reena was born on Friday
Reena (562 days + 75 weeks) → 562 + 75 × 7 ⇒ 562 + 525 days ⇒ 1087 days
Odd days = 1087 ÷ 7 → 2 odd days
So, Reena is 2 days older than Suresh.
Reena → Friday
Suresh → Friday - 2 ⇒ Wednesday
Hence, "Option 1" is the correct answer.
Fill in the blank space to the right of the symbol ∶ ∶ from the given options.
12 ∶ 35 ∶ ∶16 ∶ _______
40
53
49
63
Correct answer
63
Why this answer is correct
The logic followed here is:
12 ∶ 35
(12 ÷ 2)2 - 1 = 35
(6)2 - 1 = 35
36 - 1 = 35
35 = 35 (LHS = RHS)
Similarly,
16 ∶ ____
(16 ÷ 2)2 - 1 = ?
(8)2 - 1 = ?
64 - 1 = ?
63 = ?
Hence, "Option 4" is the correct answer.
Alternate Method
12 ∶ 35 → 12 × 3 - 1 = 35
16 ∶ __ → 16 × 4 - 1 = 63
If 'BASIC' has been coded as 'DDULE' in a language, then how will you write 'LEADER' in this language?
NHCGGU
NGCFGT
OHDGHU
OGDFHT
Correct answer
NHCGGU
Why this answer is correct
The logic followed here is:
'BASIC' has been coded as 'DDULE'
Similarly,
'LEADER' has been coded as
Hence, the correct answer is "Option 1".
If 3 + 9 = 31;
15 + 12 = 45;
18 + 9 = 36
then
12 + 27 = ?
94
14
49
53
Correct answer
94
Why this answer is correct
The logic followed here is:
In 3 + 9 = 31 →
(3 ÷ 3) and (9 ÷ 3) = 1 and 3 = 13 Reverse 31
In 15 + 12 = 45 →
(15 ÷ 3) and (12 ÷ 3) = 5 and 4 = 54 Reverse 45
In 18 + 9 = 36 →
(18 ÷ 3) and (9 ÷ 3) = 6 and 3 = 63 Reverse 36
Similarly;
In 12 + 27 = ? →
(12 ÷ 3) and (27 ÷ 3) = 4 and 9 = 49 Reverse 94
Hence, "Option 1" is the correct answer.
In a code language, 'SHOOT' has been coded as 21 - 10–17 - 17 - 22. How will you code 'TELLY' in this language?
18 - 10 - 12 - 12 - 2
22 - 7 - 20 - 14 - 6
22 - 7 - 14 - 14 - 27
7 - 22 - 10 - 12 - 9
Correct answer
22 - 7 - 14 - 14 - 27
Why this answer is correct
The logic followed here is:
'SHOOT' has been coded as 21 - 10–17 - 17 - 22
Similarly,
'TELLY' has been coded as
Hence, the correct answer is "Option 3".
