After interchanging the given two numbers and two signs what will be the values of equation (I) and (II) respectively? (\times) and +, + 3 and 9 I. (7 \times 9-8 \div 2+3) II. (4 \times 9-3+8 \div 2)
Options
- A0,1
- B
- C6,0
- D12,13
Correct answer
B.
Step-by-step solution
According to the question, after interchanging the given two signs and two numbers i.e : - (\times) and + - Two numbers 3 and 9 So, () II. (4+3-9 \times \underline{8 \div 2}) (\Rightarrow 4+3-\underline{9 \times 4}) (\Rightarrow \underline{4+3}-36) (\Rightarrow \underline{7-36}) (\Rightarrow-29) Here, values of equation (I) and (II) are (-26) and (-29) respectively. Hence, "Option - (2)" is the correct answer.
