The relation between T, k, x and y is `T = (k*x)/y`

If k, x and y are increased by 20%, the result is

`T' = (k*1.2*x*1.2)/(y*1.2)`

 = `((k*x)/y)*(1.2*1.2/1.2)`

= `(k*x)/y*1.2`

= `T*1.2`

The percentage increase in T is 20%.

T=KX/Y

k=120/100K

x=120/100X

y=120/100Y

t=1.2K*1.2X/1.2Y

t=1.2T

1.2-1

0.2*100

=20
