well the range is the difference between the lowest and the biggest term, honestly this was like the examiner saying..."here you go buddy, some free marks for you"...
dont mind, even einstien would stumble onto questions at times...

 

[Spidey21]

and the biggest term was i guess 4 minutes and the smallest was 75 seconds
4 mins = 240 secs
240 - 75 = 165
165 secs = 2 min 45 secs..
TA DA!!

the part for rotational symmetry that is 4)a)i)a is order 3 try using the centre of the shape as the invariant point and rotate it, (one trick of doing it think about it as a stencil u have of this shape and u take the shape out and rotate it and fix it u will see u can do it 3 times !

by what angle should i rotate it

 

[Tharindu]

its not allowed but people do take it and use it without any one knowing abt it !
