What is the solution of the equations x - y = 0.08 and 1(x + y)-1 = 2 ?  Select.
A) x = 3.2, y = 2.3  B) x = 1, y = 0.1  C) x = 2, y = 1.1  D) x = 0.065, y = 0.735  E) None
Answer   x - y = 0.8 ...(i)   and 1(x + y)-1=2   ⇒ 1/ (x + y) = 2   ⇒ 2(x + y) =1   ⇒ x + y = 1/2 ...(ii)   On solving Eqs.(i) and (ii),we get   x = 0.065   and y = 0.735   Correct Option: x = 0.065, y = 0.735
