Detailed Solution
Download Solution PDFGiven equation placeholders: (12 * 7 * 6) * 13 * 6
Option 1: +, -, ÷, =
(12 + 7 - 6) ÷ 13 = 6
(12 + 7 - 6) ÷ 13
= (19 - 6) ÷ 13
= 13 ÷ 13
= 1 ≠ 6 (Incorrect)
Option 2: ×, -, +,
(12 × 7 - 6) + 13 = 6
(12 × 7 - 6) + 13
= (84 - 6) + 13
= 78 + 13
= 91 ≠ 6 (Incorrect)
Option 3: ÷, +, -,
(12 ÷ 7 + 6) - 13 = 6
(12 ÷ 7 + 6) - 13
= (1.71 + 6) - 13
= 7.71 - 13 ≠ 6 (Incorrect)
Option 4: ×, -, ÷,
(12 × 7 - 6) ÷ 13 = 6
(12 × 7 - 6) ÷ 13
= (84 - 6) ÷ 13
= 78 ÷ 13
6 = 6 (Correct)
Thus, the given equation is "×, -, ÷, =".
Hence, the correct answer is "Option 4".
