Hint 2 of 2
Paint a cell only when its value is exactly 24.
Show solution
Approach: evaluate each cell and paint the ones equal to 24
- Top row: 28−4 = 24, 4×6 = 24, 18+6 = 24 — all three are painted.
- Bottom row: 19+6 = 25, 8×3 = 24, 29−6 = 23 — only the middle one is painted.
- So the whole top row is shaded and only the middle of the bottom row is, which is picture C.
