Input torque for a transmission is 15 FT*LB with a ratio of 2.3:1 and single mesh efficiency of 98.5%. What is the output torque?

Torque ratio is the ratio of the OUTPUT TORQUE to the INPUT TORQUE = 2.3:1  (given)

 

so the out put will be 2.3 times the input     15 ft lb x 2.3 = 34.5 ft lb    BUT some of the torque energy is lost in the meshing gears, so out put is only 98.5%         34.5 (.985) = 33.98 ft lb

 

I am not positive here.

Wow Pavlov you've sure moved on up on the leaderboard... Credit to your intellectual expanse.
