Given: (15 + 9 × (4 × 5)) - (3 ÷ 1) ÷ 2
As per the question-
- | ÷ |
× | + |
÷ | × |
+ | - |
after interchanging the signs we get following equation-
(15 - 9 + (4 + 5)) ÷ (3 × 1) × 2
Following the BODMAS rule (Bracket, Orders (i.e. powers and square roots, etc.), Division and Multiplication, Addition and Subtraction):
1. Bracket (): (15 - 9 + 9) ÷ 3 × 2
15 ÷ 3 × 2
2. Division (÷): 5 × 2
3. Multiplication (×): 10
Final answer is (b) 10.
