If x/2y = 3/2, the value of (2x + y) / (x

Home » Aptitude » Simplification » Question

If x/2y = 3/2, the value of (2x + y) / (x - 2y) equals ?

1. 1/7
2. 7
3. 7.1
4. None of these

Correct Option: B

Given expression = 2x + y / x - 2y
Dividing Num and Denom by y we get.
= [2(x/y) + 1] / [(x/y) - 2] = (2 x 3 + 1) / (3 - 2) = 7/1 = 7
[ ∵ x/2y = 3 / 2 ⇒x/y = (3 / 2 x 2) = 3 ]
