If a/b = 5/4, Then (4a + 3b) / (4a - 3b) = ? Choose the correct choice from the following answers: A) 7 B) 6 C) 3 D) 5 E) 4

Rationale: "answer dividing numerator as well as denominator by b , we get given exp . = ( 4 a + 3 b ) / ( 4 a - 3 b ) = ( 4 a / b + 3 ) / ( 4 a / b - 3 ) since a / b = 5 / 4 this implies that = [ ( 4 * 5 ) / 4 + 3 ] / [ ( 4 * 5 ) / 4 - 3 ) ] = ( 5 + 3 ) / ( 5 - 3 ) = 4 option : e"
Answer: E
