Can you solve this GEP question?

[SPARKTEACHER]

Study the pattern below carefully and find the missing alphabet.
Z，Y，W, T, P, _______
(1) K
(2)L
(3)M
(4)N

This is pattern question, compare the order of the alphabet, Z is the 26th letter in the alphabet, Y is the 25th letter, W is the 23 letter, T is 20, P is 16. Convert letters into numbers according to the order of each letter in the alphabet
26, 25, 23, 20, 16, _______
Now, we can easily see the next number is 11, and the 11th letter in the alphabet is K.

Day 1
There is a book on the table. The pages number ranges from 1 to 100. Then any page number that contains the digit 3 is entirely erased. What is the sum of all of the numbers that were erased?

It's 10 (from 30-39) and 9 (3, 13, 23, 43, ...) so = 10+9 = 19. So am I in GEP?

Correct meh?
I read many times...still don;t think it's the number of pages

Oh... so must add up all the numbers? Geez.

Ya good spotting.

Sometimes if just miss a tiny detail or interpret wrongly will have zero marks. Even though u can tell the brain has processed the concept correctly. This is my gripe about SG education system. Only rewards meticulous personality types. U dont seriously need to be for many professions out there. And not many grown adults are either.

Found this from a P5 SA2 exam:

This type of qn is asked in P6 nowadays.

This type of qn is asked in P6 nowadays.

I'll move on to the next question
I mean, it's actually fun and challenging, esp for the more maths-inclined to find the fastest way to add up the numbers. But there still a huge risk in wrong computation after you figure out the pattern.
