Here, we will check all the options as:
1) ÷, +, - and ×
Applying the signs, we will get,
⇒ 8 ÷ 4 + 2 - 6 × 3 = 19
Using the BODMAS rule, we will get,
⇒ 2 + 2 - 6 × 3 = 19
⇒ 2 + 2 - 18 = 19
⇒ - 14 = 19, is not possible
2) +, ×, - and ÷
Applying the signs, we will get,
⇒ 8 + 4 × 2 - 6 ÷ 3 = 19
Using the BODMAS rule, we will get,
⇒ 8 + 4 × 2 - 2 = 19
⇒ 8 + 8 - 2 = 19
⇒ 14 = 19, is not possible
3) ×, ÷, - and +
Applying the signs, we will get,
⇒ 8 × 4 ÷ 2 - 6 + 3 = 19
Using the BODMAS rule, we will get,
⇒ 8 × 2 - 6 + 3 = 19
⇒ 16 - 6 + 3 = 19
⇒ 13 = 19, is not possible
4) ×, ÷, + and -
Applying the signs, we will get,
⇒ 8 × 4 ÷ 2 + 6 - 3 = 19
Using the BODMAS rule, we will get,
⇒ 8 × 2 + 6 - 3 = 19
⇒ 16 + 6 - 3 = 19
⇒ 19 = 19, is possible
Thus, the correct sequence of signs used is '×, ÷, + and - ' for balancing the following equation.
Hence, the correct answer is 'option 4'.
