Answer 1

Correct Answer - Option 4 : 9

Given:

+	-	×	÷
Means
×	+	÷	-

 

Given Equation :

21 ÷ 8 + 2 − 12 × 3 =?

Arranging according to the given conditions:

21 - 8 × 2 + 12 ÷ 3 =?

Applying BODMAS rule:

21 - 8 × 2 + 12 ÷ 3 =?

21 - 8 × 2 + 4 = ?

21 - 16 + 4 = ?

25 -16 = ?

? = 9

Hence, ‘9’ is the correct answer.
