Let us check all the options one by one.
From option (a),
6 - 5 + 4 = 34 (using VBODMAS rule)
? 10 - 5 = 34 ? 5 = 34
? LHS ? RHS
So, option (a) is incorrect
From option (b),
6 x 5 + 4 = 34 (using VBODMAS rule)
? 30 + 4 = 34 ? 34 = 34
? LHS = RHS
So, option (b) gives us the correct answer and hence, there is no need to check remaining options.
? 6%12C3@8 $ 3 = ?
After replacing the sign according to the question
? 6 + 12 ÷ 3 x 8 - 3 = ?
Apply the BODMAS Rule
? 6 + 4 x 8 - 3 = ?
? 6 + 32 - 3 = ?
? 38 - 3 = ?
? ? = 35
After replacing the sign according to question
1 P 45 R 2 Q 2 S 4
Apply the BODMAS Rule
= 1 + 45 ÷ 2 x 2 - 4
= 1 + 22.5 x 2 - 4
= 1 + 45 - 4 = 42
As, 4 - 4 ? 4 x 4 + 1 = 17
6 - 6 ? 6 x 6 + 1 = 37
2 - 2 ? 2 x 2 + 1 = 5
Similarly, 5 - 5 ? 5 x 5 + 1 = 26
? ? = 26
Given, 40* 2* 4 * 3 * 8
Let us check all the options one by one.
From option (a), putting the signs in given equation, we get
40 + 2 - 4 ÷ 3
= 8 ? 42 - 4/3 = 8
? 126 - 4 = 24 ? 122 = 24
? L H S ? R H S
So, option (a) is incorrect.
From option (b), putting the signs in given equation, we get
40 ÷ 2 + 4 = 3 x 8
? 20 + 4 = 24 ? 24 = 24
LHS = RHS
Hence, option (b) is correct and there is no need to check remaining options.
Given expression, (50 x 2) W (28 T 4)
After interchanging the letters with symbols, we get
(50 ÷ 2) + (28 x 4) = 25 + 112 = 137
Let us check all the options one by one.
From option (a),
65 - 40 + 11 = 36 ? 76 - 40 = 36
? 36 = 36 ? LHS = RHS
So, option (a) is correct and hence there is no need to check remaining options.
Given, 7 * 7 * 2 * 1 = 12
Let us check all the options one by one.
From option (a), putting the signs in given equation, we get
7 x 7 - 2 ÷ 1 = 12 ? 7 x 7 - 2 = 12
? 49 - 2 = 12 ? 47 = 12
? LHS ? RHS
So, option (a) is incorrect.
From option (b), putting the signs in given equation, we get
7 + 7 - 2 x 1 = 12 ? 7 + 7 - 2 = 12
? 14 - 2 = 12 ? 12 = 12
Hence, option (b) is correct and there is no need to check remaining options .
As, 73 + 82 = 14
? (7 - 3) + (8 + 2) = 14
? 4 + 10 = 14
? 14 = 14 and 91 + 21 = 11
? (9 - 1) + (2 + 1) = 11
? 8 + 3 = 11 ? 11 = 11
Similarly, 86 + 24 = (8 - 6) + (2 + 4) = 2 + 6 = 8
From option (b),
24 = 4 x 5 + 4
? 24 = 20 + 4 ? 24 = 24
Apply all option one by one
? 16 x 6 ÷ 4 = 24
? 96/4 = 24 ? 24 = 24
