pick some easy values to work with ...
let S = 2
k = 6
T = 3
T = k/S
3 = 6/2
increase S by 50% ...
T = 6/3
T = 2
T changes from 3 to 2 ... a 33 1/3 % decrease
Hello,
another quantitative reasoning question from my GRE booklet that I desperately need help with :
The quantities of S and T are positive and related by the equation S= k/T where k is a constant. If the value of S increases by 50%, then the value of T decreases by what percent?
a) 25%
b) 33 1/3 %
c) 50%
d) 66 2/3 %
e) 75%
Any suggestions appreciated !
