6. (10 points) After Sun Wukong obtained the如意金筂棒, the little monkeys were all envious, so Sun Wukong went to the Kingdom of Ao Lai to borrow weapons to distribute to them. It is known that Sun Wukong borrowed a total of 600 pounds of weapons, and each weapon does not exceed 30 pounds. The little monkeys need to carry the weapons back, but each little monkey can carry a maximum of 50 pounds. To ensure that all the borrowed weapons are taken back, the minimum number of little monkeys needed is $\qquad$ (Sun Wukong does not carry weapons).
【Answer】Solution:
Since $600 \div 25=24$ (only)
Therefore, when 600 is divided by a number greater than 25, the quotient is less than 24.
For example: $600 \div 25.1 \approx 23.9$, rewritten as $600=23 \times 25.1+22.7$, this 22.7 kg plus $25.1<50$ hence the answer is 23.
