324 + 12 × 6 - 21 ÷ 3 = ?

1. 387
2. 390
3. 385
4. 489

Answer 1

Correct Answer - Option 3 : 385

Given equation is: 

324 + 12 × 6 - 21 ÷ 3 = ?

On interchanging the symbols '+' with '-' and '×' with '÷' we get,

= 324 - 12 ÷ 6 + 21 × 3 

= 324 - 2 + 21 × 3

= 324 - 2 + 63

= 387 - 2 

= 385

Hence, "385" is the correct answer.
