This time, I will present three problems with letters.
Problem 1:
Divide the letters of the alphabet into four groups:
Group 1: A, M, T, U, V, W
Group 2: B, C, D, E, K
Group 3: H, I, O, X
Group 4: F, G, J, L, N, P, Q, R, S
In which group should we place the missing letters (Y and Z)?
Problem 2: What is the next letter in this series: OTTFFSSEN?
Problem 3: What is the next letter in this series: MVEMJSUN?

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
