If p/q =4/5, then the value of 18/7 + {(2q - p) / (2q + p)} is ? Pick:  A) 3 / 7  B) 34  C) 1  D) 2  E) 3

Rationale: "answer given exp . = 18 / 7 + { ( 2 q - p ) / ( 2 q + p ) } dividing numerator as well as denominator by q , exp = 18 / 7 + { 2 - p / q ) / ( 2 + p / q ) } = 18 / 7 + { ( 2 - 4 / 5 ) / ( 2 + 4 / 5 ) } = 18 / 7 + 6 / 14 = 18 / 7 + 3 / 7 = 21 / 7 = 3 correct option : e"
Answer: E
