Given equation:- 19 + 63 ÷ 7 – 8 × 12 = 79
By interchanging two signs,
1) × and ÷
19 + 63 × 7 – 8 ÷ 12 = 79
19 + 441 – 0.67 = 79
460 – 0.67 = 79
459.33 = 79
2) – and ×
19 + 63 ÷ 7 × 8 - 12 = 79
19 + 9 × 8 – 12 = 79
19 + 72 – 12 = 79
91 – 12 = 79
79 = 79
Here, option 2 is true so no need to check the remaining option.
Thus, the correct answer is “- and ×”.
