Help with exam question - TAS, EAS, CAS

Not sure if this is the right place to post but here goes; i need help with the solution to the following question, any help is much appreciated!

An airliner undergoing certification tests and the manufacturer wishes to evaluate its performance under 'hot and high' conditions. A point of interest is the landing speed at a typical airport at high elevation, and the test location is chosen to be Denver, Colorado (elevation 1655m).

(i) The aircraft has a predicted approach airspeed of 150 KEAS. Find the corresponding values of CAS and TAS in the ISA +25 degrees C atmosphere at a height of 345m. Take MSL pressure to be the ISA value.

(ii) Calculate the pressure altitude corresponding to the air pressure at the point described in part (i).

Again any help much appreciated!!!!
