If a/b = 5/4, Then (4a + 3b) / (4a - 3b) = ?
Select the correct option
A) 7  B) 6  C) 3  D) 5  E) 4
Answer   Dividing numerator as well as denominator by b, we get   Given Exp. = (4a + 3b) / (4a - 3b) = (4a/b + 3) / (4a/b - 3)   Since a/b = 5/4   this implies that   =[(4*5)/4 +3]/[(4*5)/4 -3)]   = (5+ 3) / (5 - 3)=
