If p/q =4/5, then the value of 25/7 + {(2q - p) / (2q + p)} is ?
Choose the correct answer.
A) 4
B) 34
C) 1
D) 2
E) 3

Rationale: "answer given exp . = 25 / 7 + { ( 2 q - p ) / ( 2 q + p ) } dividing numerator as well as denominator by q , exp = 25 / 7 + { 2 - p / q ) / ( 2 + p / q ) } = 25 / 7 + { ( 2 - 4 / 5 ) / ( 2 + 4 / 5 ) } = 25 / 7 + 6 / 14 = 25 / 7 + 3 / 7 = 28 / 7 = 4 correct option : a"
Answer: A
