Hi all,

I have find the attached maths questions really challenging and many of these require you to think with pen and paper. These are provided with explanations.

So try them.

Regards.

Thanks for the questions..Kudos.

By the way, I don't agree with the answer to question 1.

You said n=79, but if n=79 then we would have:
2+4+6+8+....+78 = 2(1+2+3+4+....+39) = 2 (39*40/2) = 39*40.

Ithink the answer should be 159.

2+4+6+...+158 = 2(1+2+3+..+79) = 2(79*80/2) = 79*80.

Hi,

You are correct. Even I have noticed this error before.

If you have some more issues then you can search on GmarClub. Almost all difficult ones are discussed.
