### KS Comments:

Students should be careful when they substitute. Very easy to make a careless mistake here. No need to actually rearrange the question actually. And since the question wants answers in 3 dp for (i) and (ii), but didn’t state anything for (iii) we should round off to 3 significant figures as per normal.
