Q.
99% have failed to solve this. Answer it ?
A.
Answer is 7.
As per rules of mathematics, we need to apply BODMAS ( Brackets, Orders (powers and roots), Division and Multiplication, Addition and Subtraction) and follow the order of operation. So, solving it will give:
a) 6 – 1 x 0 + 1 (because 2/2 is one and division takes the priority as order of operation because of BODMAS)
b) 6 – 0 + 1 (because 1 x 0 is 0 )
c) 7 – 0 ( Addition takes priority as order of operation over subtraction because of BODMAS)
d) 7 ( because 7 – 0 is 7)
