TA Portion in mileage

STORY OF INJUSTICE:

The mean of pay of Loco Pilot (Pass) is {(9300 + 34800) / 2} + 4200 = Rs 26250/- The 30% pay element is Rs.7875/-.

One LP Passenger undergoing training for one month will get 30 x 270= Rs.8100 as ALKM

So what is the TA portion in that:

8100-7875=RS.225/-

Whether this is JUSTIFIED ?

One Station Master in 4200 GP, who is undergoing training, will get 30 x 425=12750/- as TA.
