If '-' stands for '÷', '+' stands for '-', '÷' stands for 'x', 'x' stands for '+', then which one of the following equation is correct?

1. 70 - 2 + 4 ÷ 5 x 6 = 44
2. 70 - 2 + 4 ÷ 5 x 6 = 21
3. 70 - 2 + 4 ÷ 5 x 6 = 341
4. 70 - 2 + 4 ÷ 5 x 6 = 96

Correct Option: B

Change the proper sign according to question and try all option one by one by applying the BODMAS Rule.
'-' ⇒ ÷
'+' ⇒ '-'
÷ ⇒ 'x'
'x' ⇒ '+'
∴ 70 ÷ 2 - 4 x 5 + 6 = 21
⇒ 35 - 20 + 6 = 21
⇒ 15 + 6 = 21
⇒ 21 = 21
