In a class of 20 students, Alisha’s rank is 15th from the top. Manav is 4 ranks above Alisha. What is Manav’s rank from the bottom?
Show Hint
When calculating a person's rank from the bottom, remember the formula: \[ \text{Rank from bottom} = \text{Total students} -\text{Rank from top} + 1. \] This is a quick way to switch between ranks from top and bottom.
