Option 3 : 12 - 12 ÷ 6 × 6 + 3 = 21

By decoding:

+	-	×	÷
Means
×	+	÷

Using BODMAS rule

Option 1:

30 - 8 ÷ 4 +6 × 1 = 32

30 - 2 + 6 = 32

36 - 2 is not equal to 32

Option 2:

8 × 5 + 20 ÷ 4 - 6 = 41

8 × 5 + 5 - 6 = 41

40 + 5 - 6 =41

- 6 ≠ 41

Option 3:

12 - 12 ÷ 6 × 6 + 3 = 21

12 + 12 - 6 ÷ 6 × 3 = 21

12 + 12 - 1 × 3 =21

12 + 12 - 3 = 21

24 - 3 = 21 is correct

Option 4:

6 + 7 × 3 - 4 ÷ 6 = 26

6 × 7 ÷ 3 + 4 - 6 = 26

6 × 2.3 + 4 - 6 = 26

13.8 + 4 - 6 =26

11.8 is not equal to 26

Hence, option 3 is correct
