A) \[36-\,6+5\times 4\div 2=27\]
B) \[30+6-\,5\div 4\times 2=30\]
C) \[30\times 6\div 5-\,4+2=32\]
D) \[30\div 6\times 5+4-\,2=40\]
Correct Answer: A
Solution :
[a] \[30-6+5\times 4\div 2=27\] \[\Rightarrow 30\div 6\times 5+4-\,2=27\] \[\Rightarrow \,\,25\text{ }+\text{ }4-\,2\Rightarrow \,\,27=27,\]Option [a] is correct \[30+6-\,5\div 4\times 2=30\] \[\Rightarrow 30\times 6\div 5-4+2=30\] \[\Rightarrow 36-\,4+2\ne 30,\]Option [b] is wrong \[30\times 6\div 5-\,4+2=32\] \[\Rightarrow 30+6-\,5\div 4\times 2\ne 32,\]Option [c] is wrong \[\Rightarrow 30\div 6\times 5+4-\,2=40\] \[\Rightarrow 30-\,6+5\times 4\div 2\ne 40\] Option [d] is wrong.
