3. (3 points) A unit held a spring tea party, and bought 4 boxes of apples of the same weight. After taking out 24 kilograms from each box, the sum of the remaining weights of apples in each box was exactly equal to the weight of one box originally. Then the original weight of each box of apples was $\qquad$ kilograms.

【Solution】Solution: $(24 \times 4) \div(4-1)$,
$$

=96 \div 3, \\
=32 \text { (kilograms); }
\end{array}
$$

Answer: The original weight of each box of apples was 32 kilograms.
