A stood 10th in the class, while B ranked 38 from the bottom. B's result is better than A and there are 2 students between A and B. Total number of students are
- a.40
- b.41
- c.42
- d.44
Answer: (D) 44
B did better than A and exactly two students stand between them, so B's rank from the top is $10-3=7$. B is thus 7th from the top and 38th from the bottom, and the total number of students is $7+38-1=44$. The general rule is: total = (rank from top) + (rank from bottom) − 1, because the person concerned is counted twice. Had B been worse than A, B would have been 13th from the top and the total would have been 50, which is not among the options.
