Qb: Ans is L as have only one pair of perpendicular lines

Count carefully how many pairs of perpendicular lines I had marked out in the letter "E".

for (a), S also has parallel lines. Notice that the two lines are of equal distance to each other.

You marked out 3 pairs correct?

Question asked for only 1 pair. Up to you to decide if "E" is an answer.

Thanks Rye for clearing my doubts on this Q! Now I more confident with my ans

I suppose this kind of question requires use of a protractor.

Alternatively, you may just use a ruler. But a protractor is always safer.

And adding on, I would say this question is actually poorly set..... These are most likely also right angles.

Perhaps they meant angles in the diagram

That would all come down to the phrasing of the question... Maybe it should have stated "... in the enclosed diagram below"

Or perhaps "... within the following diagram/figure"

Since none of them a labeled as right, I'd say zero since one cannot assume perpendicular line. The question should ask how many angles "appear" to be right.

Since the question is asking for how many 5-mark questions there are, we will assume all questions to be 3-mark questions to save some time. Assuming all are 3-mark questions, total marks = 3 x 15 = 45 Shortage of marks = 65 - 45 = 20 Number of 5-mark questions = 20 / (5-3) = 10. Hence, there are 10 5-mark questions.

Thxs u I missed out the last impt step

You can also work backwards by assuming all 15 questions are 5 mark questions. (15 x 5 = 75) Then, you will realise that 75 is TEN MORE than 65. Since a 5-mark question is TWO MORE than a 3-mark question, how many 'TWO MORE' questions do we have? 10/2 = 5 So, deduct 5 5-mark questions from 15 5-mark questions to get 10 5-mark questions. 15-5=10 :)

Are you able to explain why you did these 2 steps? Whats the significance of "3" and "30"?

30 is the total units , but I don't know what is the significance for 3 .

Thats it. So know which is the correct one?

1?

Yes.

And there is also one other way to check

What's the other way ?

Hope this helps

Thank you all !

Haha, i like this.

Thank you !

The sticker is in the "JUST NICE" position!

Thank you! Got it!!!
