If '-' stands for 'addition', '÷' for 'multiplication', 'x' for 'subtraction' and '+' for 'division', then which of the following is correct ?

1. 25 x 12 -14 ÷ 4 + 6 = 16
2. 25 - 12 + 14 ÷ 2 x 4 = 15
3. 25 - 15 + 5 ÷ 4 x 16 = 21
4. 25 + 11 - 4 ÷ 10 x 6 = 20

Correct Option: C

Solve All option one by one.
After changing the Sign.
25 + 15 ÷ 5 x 4 - 16 = 21
Apply the BODMAS Rule,
⇒ 25 + 3 x 4 - 16 = 21
⇒ 25 + 12 - 16 = 21
⇒ 37 - 16 = 21
∴ 21 = 21
