8. Niko counted a total of 60 birds perching in three trees. Five minutes later, 6 birds had flown away from the first tree, 8 birds had flown away from the second tree and 4 birds had flown away from the third tree. He noticed that there was now the same number of birds in each tree. How many birds were originally perched in the second tree?
A 14
B 18
C 20
D 21
E 22
8. E Let the number of birds remaining in each tree be $x$. Therefore $x+6+x+8+x+4=60$, which has solution $x=14$. Hence the number of birds originally perched in the second tree is $14+8=22$.
