Answer 1

hEY ....

A=B-C ------
B=C-D ----
C=D-A ---------(3)

Adding (1) , (2) and (3)

     C= - 2A

Putting this value of C in (1)

We get B= -A

And outing the value of C in (3)

We get D= -A

 

Now put these values of B, C and D in terms of A in the required expression to get

 

A/-A + A/2A + 2A/A + -A/A

= ½
