Consider two ${\mathrm{I}}^{\mathrm{st}}$ order relations at $25^{\circ }\mathrm{C}$ with same initial concentrations of 1 M

I.$\mathrm{A}\stackrel{{\mathrm{t}}_{1/2}=40\min }{\to }$ product (temperature coefficient $=2$ )

II.$\mathrm{B}\stackrel{{\mathrm{t}}_{1/2}=30\min }{\to }$ product (temperature coefficient $=3$ )

If both reaction are carried out at 35ºC. and the ratio of concentrations of A & B after one hour is x : 1, the value of 'x' is-
