Discrete Mathematics
Level
2
There's a randomly ordered line of 15 forks and 15 spoons on the counter. Chef Nidhi only needs 5 forks and 5 spoons.
Can she always pick up exactly what she needs by selecting 10 consecutive utensils starting from somewhere in the line-up?
The forks and spoons are not necessarily in this order. They can be in any order.
