By interchanging the given two signs and numbers which of the following equation will be correct?
–and +, 6 and 3

Correct option is B

By interchanging the given two signs and numbers (– and +, 6 and 3), which of the following equation will be correct?
Option (A)Original:
7–3×2÷6+4=17
7+6×2÷3–4
= 7+(6×2)÷3–4
= 7+12÷3–4
= 7+4–4
= 7 ≠ 17

Option (B) Original
8×3–6+4÷2=49
Swap (– ↔ +, + ↔ – , 6 ↔ 3):
8×6+3–4÷2
= 8×6+3–(4÷2)
= 48+3–2
= 51–2
= 49 Correct

Option (C)
Original:
7+6÷3×8–5=35
Swap (– ↔ +, + ↔ – , 6 ↔ 3):
7–3÷6×8+5
= 7–(3÷6×8)+5
= 7–(0.5×8)+5
= 7–4+5
= 8 ≠ 35

Option (D)
Original:
9–6×4+3×7=8
Swap (– ↔ +, + ↔ – , 6 ↔ 3):
9+3×4–6×7
= 9+12–42
= 21–42
= −21 ≠ 8
Final Answer: (B) 8 × 3 – 6 + 4 ÷ 2 = 49
