In a row of students, Sahil is 15th from the top and 28th from the bottom. How many students are there in the row?
42
43
44
41
42
Total students = (Rank from top + Rank from bottom) - 1. Subtracting 1 is essential because the individual is counted twice (once from each end).
Total students = (Rank from top + Rank from bottom) - 1. Subtracting 1 is essential because the individual is counted twice (once from each end).
Identify given data
Sahil's position from the top is 15th and from the bottom is 28th.
Apply the formula
Total number of students = (15 + 28) - 1 = 43 - 1 = 42.
B: 43 is the sum of ranks without subtracting the overlap. C: 44 results from adding 1 instead of subtracting. D: 41 is a miscalculation error.
A is correct because when an individual's rank is known from both ends, the total count is the sum of those ranks minus one to avoid double-counting the individual.
Always verify if the question asks for total students or students standing 'between' two people; if it asks for people between two ranks, the formula changes to (Difference of Ranks - 1).
