GRE : Quantitative Comparison Problem
This is the Quantitative Comparison Problem-7.Understand the basic mathematical principles behind this problem and other problems.
Y = 3X/4: X = 2Z/3 and Z = 20
Column A : Y
Column B : 11
Since as per the information given,
Z = 20
X = 2Z/3
= X = 2 x 20/3
= X = 40/3
Y = 3X/4
= Y = [3 x 40/3] / 4
= Y = 3 x [40/4x3]
= Y = [3 x 40]/ 12
= Y = 120/12
= Y = 10.
So, B is greater than A.
So, the answer is B.
