13. (6 points) Big Monkey picked some peaches and distributed them among a group of little monkeys. If two of the little monkeys each got 4 peaches, and the rest each got 2 peaches, there would be 4 peaches left; if one of the little monkeys got 6 peaches, and the rest each got 4 peaches, there would be a shortage of 12 peaches. Big Monkey picked $\qquad$ peaches in total, and there are $\qquad$ little monkeys in the group.
【Answer】Solution: If each little monkey gets 2 peaches, there will be $2 \times 2+4=8$ left. If each monkey gets 4 peaches, there will be a shortage of $12-2=10$. Therefore, the total number of monkeys is: $(8+10) \div(4-2)=9$ (monkeys), and the total number of peaches is: $4 \times 9-10=26$ (peaches). Therefore, the answers are: 9, 26.
