If 0.764 B = 1.236 A, then what is the value of (B - A)/(B + A) ?
Choose the correct option
A) 0.764	B) 0.236	C) 2	D) 0.472	E) None
Answer   Given, 0.764 0.236 = 1.236 A   ⇒ 0.236/A = 1.236 / 0.764   Now, (0.236 - A)/(0.236 + A) = (0.236/A - 1) / (0.236/A + 1)   = (1.236/0.764 - 1) / (1.236/0.764 + 1)   = (1.236 - 0.764)/(1.236 + 0.764)   = 0.472/2.000=
