BODMAS Rule:

Given the interchange rules:

‘+’ and ‘−’ are interchanged.

‘×’ and ‘÷’ are interchanged.

Now,

Given e×pression: 54 ÷ 11 + 272 × 8 − 114

After replacing the symbols with their meanings:

⇒ 54 × 11 − 272 ÷ 8 + 114

Perform operations according to BODMAS/PEMDAS:

⇒ 54 × 11 − 272 ÷ 8 + 114

⇒ 594 − 34 + 114

⇒ 594 - 34 + 114

⇒ 560 + 114 = 674

Hence, the correct answer is "Option 1".

Given the symbol meanings:

• ‘A’ stands for ‘÷’
• ‘B’ stands for ‘×’
• ‘C’ stands for ‘+’
• ‘D’ stands for ‘−’

The given equation is:

45 B 14 A 21 D 17 C 25 = ?

Substitute the symbols with their corresponding mathematical operations:

45 × 14 ÷ 21 - 17 + 25 = ?

Now, follow the order of operations (BODMAS/PEMDAS):

45 × (14 ÷ 21) - 17 + 25

45 × (2/3) - 17 + 25

30 - 17 + 25

13 + 25 = 38

Hence, the correct answer is "Option 3".

Given Equation: 13 − 780 × 12 ÷ 16 + 32 = ?

Decoding the given information:

Now, replacing the signs in the equation:

⇒ 13 × 780 ÷ 12 + 16 - 32 = ?

Applying BODMAS Rule:

⇒ 13 × 780 ÷ 12 + 16 - 32 = ?

⇒ 13 × 65 + 16 - 32 = ?

⇒ 845 + 16 - 32 = ?

⇒ 861 - 32 = ?

⇒ 829 = ?

Hence, the correct answer is "Option 4".

Given equation: 63 ÷ 12 − 98 × 7 + 35 = ?

After interchanging ‘+’ and ‘−’ and ‘×’ and ‘÷’, we get:

63 × 12 + 98 ÷ 7 − 35 = ?

Following the BODMAS/PEMDAS rule:

= 63 × 12 + 98 ÷ 7 − 35

= 756 + 14 − 35

= 770 − 35

= 735

Hence, the correct answer is "735".

Given symbol mappings:

• ‘+’ means ‘−’
• ‘−’ means ‘×’
• ‘×’ means ‘÷’
• ‘÷’ means ‘+’

The given equation is:

502 ÷ 78 + 2 − 258 × 2 = ?

Replace the operators with their corresponding new meanings:

502 + 78 − 2 × 258 ÷ 2 = ?

⇒ 502 + 78 − 258 = ?

⇒ 580 - 250 = 322.

hence, the correct answer is "Option 1".

According to the question, after interchanging the given two signs and two numbers i.e :

• × and +
• Two numbers 3 and 9

So,

I. 7 + 3 – 8 ÷ 2 × 9

⇒ 7 + 3 - 4 × 9

⇒ 7 + 3 - 36

⇒ 10 - 36

⇒ -26

II. 4 + 3 – 9 × 8 ÷ 2

⇒ 4 + 3 - 9 × 4

⇒ 4 + 3 - 36

⇒ 7 - 36

⇒ -29

For this question, We have to check the given equation as-

146 –  2 + 3 × 123 × 5 + 2

New equation after replacing symbols-

146 ÷ 2 × 3 – 123 - 5 × 2

According to the BODMAS rule-

⇒ 73 × 3 –  123 – 5 × 2

⇒ 219 –  123 –  10

⇒ 86

Hence, Option (4) is correct.

BODMAS Table: 

Given equation I: 55 + 42 – 36 × 20 ÷ 9 = 17

Now, if '20 and 36' are interchanged, then:

⇒ 55 + 42 – 20 × 36 ÷ 9 = 17

⇒ 55 + 42 – 20 × 4 = 17

⇒ 55 + 42 – 80 = 17

⇒ 97 – 80 = 17

= 17 = 17.

LHS = RHS.

Given equation II: 20 ÷ 2 × 36 + 81 – 41 = 400

Now, if '20 and 36' are interchanged, then:

⇒ 36 ÷ 2 × 20 + 81 – 41 = 400

⇒ 18 × 20 + 81 – 41 = 400

⇒ 360 + 81 – 41 = 400

⇒ 441 – 41 = 400

= 400 = 400

LHS = RHS.

Here, Both I and II are correct equation after interchanging the given symbol.

Hence, the correct answer is "Option 3".

Given Equation: 21 + 5 × 2 – 21 ÷ 3 = 12

1) + and -

After interchanging signs

LHS = 21 - 5 × 2 + 21 ÷ 3 = 21 – 10 + 7 = 18 ≠ RHS

2) – and ÷

After interchanging signs

LHS = 21 + 5 × 2 ÷ 21 – 3 = 21 + 0.476 – 3 = 18. 476 ≠ RHS

3) – and ×

After interchanging signs

LHS = 21 + 5 - 2 × 21 ÷ 3 = 21 + 5 – 14 = 12 = RHS

4) × and ÷

After interchanging signs

LHS = 21 + 5 ÷ 2 – 21 × 3 = 21 + 2.5 – 63 = - 39.5 ≠ RHS

The logic followed is:

Decoding the information, 

Given the equation: [{(48 × 20) - (2 ÷ 4)} + (2 - 4)] ÷ 2 = ?

After replacing the signs from left to right and using the BODMAS rule,

= [{(48 - 20) + (2 × 4)} ÷ (2 + 4)] × 2 

= [{(28) + (8)} ÷ (6)] × 2

= [{36} ÷ (6)] × 2

= [6] × 2

= 12

Hence, the correct answer is "12".

The logic followed here is:

Logic: (First number ÷ 5) × 6 = Second number

• 175 ∶ 210 → (175 ÷ 5) × 6 = 35 × 6 = 210
• 310 ∶ 372 → (310 ÷ 5) × 6 = 62 × 6 = 372

Similarly,

• 295 ∶ ? → (295 ÷ 5) × 6 = 59 × 6 = 354

Hence, '354' is the correct answer.

BODMAS:

Given: 

12 - 3 = 36

21 + 3 = 7

17 × 2 = 19

15 ÷ 3 = 12 

Given equation: 144 ÷ 315 + 35 × 16 - 17

After change the sign, equation is:

⇒ 144 - 315 ÷ 35 + 16 × 17

⇒ 144 - 9 + 16 × 17

⇒ 144 - 9 + 272

⇒ 416 - 9

⇒ 407

Hence, the correct answer is "407".

BODMAS rule:

Decoding the information, 

 Given:

240 × 72 + 8 ÷ 24 – 6

After replacing the signs from left to right and using the BODMAS rule,

240 - 72 ÷ 8 × 24 + 6

= 240 - 9 × 24 + 6

= 240 - 216 + 6

= 246 - 216

= 30

Hence, “30” is the correct answer.

The logic is followed here is:

1) Vowels are shifted at first 

2) Consonants are shifted  -2 and arranged after vowel.

STABLE : AEQRZJ ⇒

And,

TARGET : AERPER ⇒

Similarly,

VISUAL : ? ⇒

Hence the correct answer is "IUATQJ".

-261 + (-380) – (-521) + 821 – (-121) = -261 – 380 + 521 + 821 + 121 = 822
