MAT Exam 2024 Paper

Concept:A fence with posts placed at equal intervals uses one extra post for the starting end, so the number of posts is the number of intervals plus one.Explanation:For Column A, the fence is $144$ feet long and posts are placed $12$ feet apart.Number of intervals $= \frac{144}{12} = 12$.Including the post at the starting end, total posts $= 12 + 1 = 13$.So Column A represents $13$ posts.For Column B, the comparison value is the number of intervals only, which is $\frac{144}{12} = 12$.Thus, Column A is $13$ and Column B is $12$.Since $13 > 12$, the quantity in Column A is larger.Answer:Option A: The quantity in Column A is greater than the quantity in Column B.
