pressure altitude etc.

Hi,

I'm trying to get a fast & simple way of calculating these questions:

1. Indicated alt. 10000ft.OAT -20C.You set 29.62" for a station which is 2500ft high.What's your actual altitude?
2. At ISA -25C, how much altitude should be added to MEA?
3.What's SSB?
4.TAT is -30c.Adiabatic temp. rise is 10 degrees, what's SAT?

Thanks!!
