If a/b = 4/3, Then (3a + 2b) / (3a - 2b) = ?	Choose the correct choice from the following.
A) 6  B) 3  C) 5  D) - 1  E) none

Rationale: answer dividing numerator as well as denominator by b , we get given exp . = ( 3 a + 2 b ) / ( 3 a - 2 b ) = ( 3 a / b + 2 ) / ( 3 a / b - 2 ) = [ ( 3 x 4 ) / 3 + 2 ] / [ ( 3 x 4 ) / 3 - 2 ] = ( 4 + 2 ) / ( 4 - 2 ) = 3 option : b
Answer: B
