Given Question is 18 Q 12 P 4 R 5 S 6
After changing the letters in to signs as per given in the question, we have
18 x 12 ÷ 4 + 5 - 6 ,
Apply the BODMAS Rule,
? 18 x 12/4 + 5 - 6
? 18 x 3 + 5 - 6
? 54 + 5 - 6
? 59 - 6 = 53
Apply All option one by one
5 + 3 x 8 - 12 ÷ 4 = 3
Now, after changing the sign for option C
5 + 3 x 8 ÷ 12 - 4 = 3
Apply the BODMAS Rule
5 + 3 x 8/12 - 4 = 3
5 + 2 - 4 = 3
3 = 3
After replacing all the symbol from question.
44 x 9 ÷ 12 - 6 x 4 + 16 = ?
Apply BODMAS rule,
? 44 x 9 x 1/12 - 24 + 16 = ?
? 33 - 24 + 16 = ?
? 49 - 24 = ?
? ? = 25
Rules
(i) (2-digit even number) ÷ ( Even number)
(ii) (Even number) x (Prime number)
(iii) (Odd number) + (Odd number)
(iv) (3-digit number) - (2-digit perfect square number)
(v) (3-digit number) ÷ (2-digit non-perfect square number)
Solution
1st Row 24 7 81 ? 24 x 7 = 168 [rule (ii)]
? 168 - 81 = 87 [rule (iv)]
= x
2nd Row x 27 19 ? 87 27 19
? 87 + 27 = 114 [rule (iii)]
? 114 ÷ 19 = 6 [rule (v)]
? Resultant of second row = 6
Rules
(i) (2-digit even number) ÷ ( Even number)
(ii) (Even number) x (Prime number)
(iii) (Odd number) + (Odd number)
(iv) (3-digit number) - (2-digit perfect square number)
(v) (3-digit number) ÷ (2-digit non-perfect square number)
Solution
1st Row 125 64 33 ? 125 - 64 = 61 [rule (iv)]
? 61 + 33 = 94 [rule (iii)]
= x
2nd Row 282 x 39 ? 282 94 39
? 282 ÷ 94 = 3 [rule (v)]
? 3 + 39 = 42 [rule (iii)]
? Resultant of second row = 42
Rules
(i) (2-digit even number) ÷ ( Even number)
(ii) (Even number) x (Prime number)
(iii) (Odd number) + (Odd number)
(iv) (3-digit number) - (2-digit perfect square number)
(v) (3-digit number) ÷ (2-digit non-perfect square number)
Solution
1st Row 97 45 71 ? 97 + 45 = 142 [rule (iii)]
? 142 ÷ 71 = 2 [rule (v)]
2nd Row 48 8 11 ? 48 ÷ 8 = 6 [rule (i)]
? 6 x 11 = 66 [rule (ii)]
? Required sum = 2 + 66 = 68
Solve All option one by one.
After changing the Sign.
25 + 15 ÷ 5 x 4 - 16 = 21
Apply the BODMAS Rule,
? 25 + 3 x 4 - 16 = 21
? 25 + 12 - 16 = 21
? 37 - 16 = 21
? 21 = 21
Solve all option one by one.
Change the symbol in given question.
From option (D),
4 A 3 M 2 L 4 D 2 M 6
4 + 3 X 2 < 4 ÷ 2 x 6
Apply the BODMAS Rule.
10 < 12
Interchange the symbol as per given in question.
6 ÷ 8 + 2 x 5 - 8
After changing the sign
= 6 x 8 ÷ 2 - 5 + 8
Apply the BODMAS Rule.
= 6 x 4 - 5 + 8
= 24 - 5 + 8 = 32 - 5 = 27
Given question is,
3 ? 6 ? 2 ? 8 ? 4 ? 5
Then, after placing of signs in given question,
3 + 6 - 2 x 8 ÷ 4 = 5
Apply the BODMAS Rule.
9 - 2 x 2 = 5
5 = 5
Solve by using all option one by one.
Choosing option (C) and change the sign.
24 = 34 ÷ 2 - 5 + 12
Use BODMAS rule to solve the equation.
24 = 17 - 5 + 12
24 = 29 - 5
24 = 24
