Question

the quantities S and T are positive and are 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?

Answer 1

50%

Answer 2

50%

Answer 3

let s= 10, t= 100 and consequently k = t*s = 1000

S increased by 50% to 10*1.5 = 15

15 = 1000/t

t= 1000/15= 66.67

% decrease = 66.67- 100/100 = 33.33%
