Hi Team. Any assistance for this one?

Hi Team, I have been trying to get through the nav stuff.The ones Im having difficulty with don't seem to have any good worked examples in teh AFT notes. Can i please get some advice on the question below?

Q: You are cruising at A070 directly above a mountain of elev 6420ft. The QNH is 1001 hpa with an OAT of -14 deg C. The radio/radar altimeter would indicate:

a) 188ft
b) 972ft
c) 390ft
d) 580ft

Apparently it is a). I was happy to remove b) and d) based on the temperature being colder than ISA (hence the altimeter overreading & the true alt being below the indicated)...but I can't work it out.

Some of the ILS above or below ones are brain breakers too...can't get the exact answers...which makes me doubt my method.

Any help on the above question would be greatly appreciated. There is a beer in it for someone in Darwin.
