An ice-cream brick is split into two halves, then one half is cut into several equal portions. Each small portion weighs 12 grams. There are 5 portions in total (4 small portions and the other half). What was the weight of the original brick?

Explanation:
When a brick is split into two equal halves, each half weighs half of the whole. The four small portions come from one half, and each portion is 12 grams, so that half weighs 4 × 12 = 48 grams. The other half has the same weight, 48 grams. Adding both halves gives the original weight: 48 + 48 = 96 grams.
