6. Squirrel mom collects pine nuts, on sunny days she can collect 20 every day, and on rainy days she can only collect 12 every day. She collected 112 pine nuts in a row for several days, averaging 14 per day. How many of these days were rainy?
6.【Solution】The squirrel collected for: $112 \div 14=8$ (days)
Assuming all 8 days were sunny, the number of pine cones collected would be: $20 \times 8=160$ (cones)
Actually, only 112 cones were collected, which means 48 fewer cones were collected: $160-112=48$ (cones)
Each rainy day results in 8 fewer cones collected: $20-12=8$ (cones)
Therefore, there were $48 \div 8=(6)$ rainy days.
