Coded Logic Question 1:
Let
Answer (Detailed Solution Below)
Coded Logic Question 1 Detailed Solution
Given:
x ⊗ y = (x - 2y) / y
4 ⊗ 5 = k ⊗ 10
Logic:
x ⊗ y = (x - 2y) / y
Calculation:
4 ⊗ 5 = k ⊗ 10
⇒ (4 - 2 × 5) / 5 = (k - 2 × 10) / 10
⇒ (4 - 10) / 5 = (k - 20) / 10
⇒ -6 × 10 = 5 × (k - 20)
⇒ -60 = 5k - 100
⇒ -60 + 100 = 5k
⇒ 40 = 5k
⇒ k = 40 / 5 = 8
The value of k is 8.
Hence, the correct answer is "Option 2".
Coded Logic Question 2:
What will be the value of the following equation if '÷' means 'addition', '+' means 'subtraction', '-' means 'multiplication' and '×' means 'division"?
72 × 9 - 3 ÷ 8 + 2 = ?
Answer (Detailed Solution Below)
Coded Logic Question 2 Detailed Solution
BODMAS Rule:
According to the question, the symbol meanings are:
| Original Symbol | ÷ | + | - | × |
| New Meaning | + | - | × | ÷ |
Now,
Given equation: 72 × 9 - 3 ÷ 8 + 2 = ?
After replacing the symbols with their meanings:
⇒ 72 ÷ 9 × 3 + 8 - 2
Perform operations according to BODMAS/PEMDAS:
⇒ 72 ÷ 9 × 3 + 8 - 2
⇒ 8 × 3 + 8 - 2
⇒ 24 + 8 - 2
⇒ 32 - 2
⇒ 30
Hence, the correct answer is "Option 1".
Coded Logic Question 3:
If # stands for ×, @ stands for ÷, ∧ stands for + and ∨ stands for –, then find the value of
6 # 13 ∧ 45 @ 3 ∨ 7 # 12
Answer (Detailed Solution Below)
Coded Logic Question 3 Detailed Solution
Given the following codes:
| Symbol | Stands for |
|---|---|
| # | × |
| @ | ÷ |
| ∧ | + |
| ∨ | – |
Expression: 6 # 13 ∧ 45 @ 3 ∨ 7 # 12
After symbol meaning.
6 × 13 + 45 ÷ 3 – 7 × 12
(BODMAS)
→ 6 × 13 + 45 ÷ 3 – 7 × 12
→ 6 × 13 + 15 – 7 × 12
→ 78 + 15 – 84
→ 9
Hence, the correct answer is "Option 2".
Coded Logic Question 4:
If 2 + 3 = 8 ; 4 + 5 = 24 ; 1 + 8 = 9, then what is 3 + 6 ?
Answer (Detailed Solution Below)
Coded Logic Question 4 Detailed Solution
The logic followed here is:
2 + 3 = 8 → (2 × 3) + 2 ⇒ 8
4 + 5 = 24 → (4 × 5) + 4 ⇒ 24
1 + 8 = 9 → (1 × 8) + 1 ⇒ 9
Similarly,
3 + 6 = ? → (3 × 6) + 3 ⇒ 21
Hence, "Option 2" is the correct answer.
Coded Logic Question 5:
If 16 * 24 = 20, 71 * 19 = 45 and 8 * 52 = 30, then what will be 35 * 27?
Answer (Detailed Solution Below)
Coded Logic Question 5 Detailed Solution
The pattern followed here is,
(first number + second number) ÷ 2 = third number
Like
(16 + 24) ÷ 2 = 40 ÷ 2 = 20
(71 + 19) ÷ 2 = 90 ÷ 2 = 45
(8 + 52) ÷ 2 = 60 ÷ 2 = 30
Similarly,
(35 + 27) ÷ 2 = 62 ÷ 2 = 31
Hence, option 4 is the correct answer.Top Coded Logic MCQ Objective Questions
Some equations have been solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.
If 45 × 72 = 9, 40 × 51 = 7, then 12 × 40 = ?Answer (Detailed Solution Below)
Coded Logic Question 6 Detailed Solution
Download Solution PDFThe pattern followed is:
Sum of first two numbers is divided by 13.
45 + 72 = 117, 117 ÷ 13 = 9
40 + 51 = 91, 91 ÷ 13 = 7
Similarly,
12 + 40 = 52, 52 ÷ 13 = 4
Therefore, ‘4’ is the correct answer.If 9 × 6 = 45, 7 × 4 = 33 and 6 × 4 = 20, then what is the value of 5 × 3?
Answer (Detailed Solution Below)
Coded Logic Question 7 Detailed Solution
Download Solution PDFThe logic here is as follows,
92 – 62 = 81 – 36 = 45
72 – 42 = 49 – 16 = 33
62 – 42 = 36 – 16 = 20
Similarly,
52 – 32 = 25 – 9 = 16
Thus, the value of 5 × 3 = 16.If each term in the given sequence is assigned number 1, 2, 3 … according to their position form the left, then the sum of the numerical values of the positions of the symbols will be __________.

Select the number from the given options that can replace the question mark(?) below:
If 243 (222) 317, then 548 (?) 621
Answer (Detailed Solution Below)
Coded Logic Question 9 Detailed Solution
Download Solution PDFGiven: 243 (222) 317
The logic follows here is:
317 - 243 = 74,
74 × 3 = 222
Similarly, to solve 548 (?) 621:
621 - 548 = 73,
73 × 3 = 219
Hence, 219 is the correct answer.
In a certain code language, if 23 + 49 = 278, and 24 + 51 = 410, then 78 + 61 = ?
Answer (Detailed Solution Below)
Coded Logic Question 10 Detailed Solution
Download Solution PDFThe logic followed here is-
- 23 + 49 = 278 → (3 × 9) ( 2 × 4) = (27) (8) → 278
- 24 + 51 = 410 → (4 × 1) (2 × 5) = (4) (10) → 410
- 78 + 61 = 842 → (8 × 1) (7× 6) = (8) (42) → 842
Hence, 842 is the correct answer.

452 F 270 H 90 = ? → 452 ÷ (270 + 90) = 5.625
Hence, the answer is ‘5.625’.If 2 * 7 # 1 = 5 and 71 * 100 # 2 = 58, then in the expression 3 * 6 # A = 30, what is the value of 'A'?
Answer (Detailed Solution Below)
Coded Logic Question 12 Detailed Solution
Download Solution PDFThe meaning of symbols used in the equations will be:
"*" Coded as -
"#" Coded as ×
Logic: (2nd number - 1st number) × 3rd number = Given number.
For,
2 * 7 # 1
⇒ (7 - 2) × 1
⇒ 5 × 1 = 5.
For,
71 * 100 # 2
⇒ (100 - 71) × 2
⇒ 29 × 2 = 58.
Similarly,
3 * 6 # A = 30
⇒ (6 - 3) × A = 30
⇒ 3 × A = 30
⇒ A = 30/3 = 10.
Hence, the correct answer is "Option (2)".
If 132 F 624 = 657 and 84 F 321 = 504, then 168 F 27 = ?
Answer (Detailed Solution Below)
Coded Logic Question 13 Detailed Solution
