If p/q =4/5, then the value of 4/7 + {(2q - p) / (2q + p)} is ?	Choose the correct choice from the following choices.
A) 3 / 7 B) 34 C) 1 D) 2 E) 3
Answer   Given Exp. = 4 / 7 + {(2q - p) / (2q + p)}   Dividing numerator as well as denominator by q,   Exp = 4/7 + {2-p/q) / (2 + p/q)}   = 4/7 + {(2 - 4/5) / (2 + 4/5)}   = 4/7 + 6/14   = 4/7 + 3/7   =7/7=
