Wolves and Owls

You are in the woods with owls and wolves. There are 22 eyes and 32 legs. How many owls and wolves are there?

5 owls and 5 wolves, (not 6 owls because 2 of the eyes and legs are yours).

2 * owls + 2 * wolves = 20 eyes
2 * owls + 4 * wolves = 30 legs
owls + wolves = 10 eyes → owls = 10 – wolves
owls + 2 * wolves = 15 → 10 – wolves + 2 * wolves = 15 → wolves = 5
owls + 5 = 10 → owls = 5

NDOLA

What does “NDOLA, PAMODZI” mean?

Thanks to the comments, it doesn’t mean anything per se, but it’s a location in Zambia. If that’s all it is, it’s not really a brain teaser, but since we’ve already worked on it, I’m marking it as solved leaving it up for posterity.

Below are former attempts to solve it.

I have yet to figure this one out. NDOLA could mean And lo, or An old, among other things. Pamodzi on the other hand didn’t have any particularly meaningful anagrams. Both words together had over 1,000 anagrams.

I haven’t come up with any other possible meanings.

Sixteen, Twenty-six, Then What?

Fill in the missing numbers in this number series.

16, 26, ?, 43, 50, ?, 61, 65, ?, 70, 71

The method to create the series is start by adding 10, then decrease the addend by 1 for each new number in the sequence. That gives us:

16 + 10 = 26
26 + 9 = 35
35 + 8 = 43
43 + 7 = 50
50 + 6 = 56
56 + 5 = 61
61 + 4 = 65
65 + 3 = 68
68 + 2 = 70
70 + 1 = 71
