| Original | × | ÷ | 4 |
| Changed | ÷ | * | 7 |
Given:
63 × 3 - 4 + 18 ÷ 7 is the equation
Calculation:
Now, interchanging 4 and 7 and also after interchanging '×' and '÷' '×' and '÷' the equation becomes,
63 ÷ 3 - 7 + 18 × 4
Now, for solving use BODMAS rule
21 - 7 + 18 × 4
= 21 + 72 - 7
= 93 - 7
= 86
Hence, the correct answer is "Option 1".
