If w/(x + y) = 1, what is the value of (x + y)/y ?
(1) x/y = 3/2
(2) y/w = 2/5
Given, w/(x + y) = 1
St1:- \(\frac{x}{y} = \frac{3}{2}\)
Or, \(\frac{x}{y}+1 = \frac{3}{2}+1\)
Or, \(\frac{x+y}{y} = \frac{5}{2}\)
Sufficient.
St2:- \(\frac{y}{w} = \frac{2}{5}\)
Or, \(w=\frac{5}{2}*y\)
Substituting 'w' in (1), we can express 'x' in terms of y, vice-versa.
Again, we can substitute the value of x or y in question stem and determine \(\frac{(x+y)}{y}\).
Sufficient.
Ans. (D)
