If V = 10x/(3y) and y ≠ 0, what is the value of V ?

(1) 5x is three times the value of one-half of 3y.

(2) y = 1/12

Given \(V=\frac{10x}{3y}\)

Find V=?For 'V' we should know the value of (x & y) OR \(\frac{x}{y}\) OR \(\frac{10x}{3y}\)

Statement 1 5x is three times the value of one-half of 3y.

=> \(5x=3*\frac{3y}{2}\)

=> \(5x*2=3*3y\)

=> \(10x=3*3y\)

=> \(\frac{10x}{3y}=3\)

=> Therefore SUFFICIENT

Statement 2 \(y=\frac{1}{2}\)

=> Value of 'y' available BUT 'x' NOT known

=> Therefore NOT SUFFICIENT

Therefore 'A'
