Megnrose,
First of all the page 60 bit. Moving into colder denser air would make your alti under-read and not over-read? Wouldn't the air pressue be higher in cold air than in warm air as pressue is a function of density? Therefore your tendancy would be to climb on the same QNH.
The cloud one (page 227) gives a way of calculating cloud bases. However, it does not take into account the dewpoint lapse rate of 5deg/1000' which would make the DALR 2.5deg/1000' and not 3deg/1000'. I noticed this from the confuser. Got the question right in the exam too.
