What do u estimate this year's cut off point to be?

Anonymous said...

15 should be 101.

Anonymous said...

Why is question 15 answer 101?

Anonymous said...

You're welcome :)

Anonymous said...

15 is NOT 101. 101 is rejected as it gives 26 and not 6.
17 is correct.

Anonymous said...

Yes, Q15 should be 17.

Yay.
Q35 is 7776?

Q35 is 2592 (2 x 6 x 6 x 6 x 6)
(im pretty sure but idk)

Firstly, A10 is always 4. 1 + 2 + ... + 10 is 55. So each group should add up to (55-4)/3 = 17.
Then, there are two possible groupings overall: 1,6,10 + 2,7,8 + 3,5,9 / 2,5,10 + 1,7,9 + 3,6,8

each group has 6 permutations, and there are 3 groups. overall, there are six possible ways to arrange the groups in the entire sequence. so 2x6x6x6x6 = 2592.

Anyone know when we can know if we get into second round or not ?

What is the cut off point estimated to be for round 2?
Will it be more that 20?

Anonymous said...

Hope not... I got 22
Last few years the COP around 10, but 2015 it became 16? So this year very hard to predict.

Anonymous said...
