If x(a + b) = y, where y ≠ 0 and 2a = 3b = 1, then y/x =

(A) 1/6
(B) 1/3
(C) 2/3
(D) 5/6
(E) 6/5


PS21159

\(2a = 3b = 1\)

So, \(a = \frac{1}{2}\) & \(b = \frac{1}{3}\)

\(x(a + b) = y\)

Or, \(x ( \frac{1}{2} + \frac{1}{3}) = y\)

Or, \(5x/6 = y\)

Hence, \(\frac{y}{x} = \frac{5}{6}\), Answer must be (D)
