In a row of students, R is 10th from left and S is 12th from right. If they interchange positions, R becomes 14th from left. Total students?

Question

Accepted Answer

1. R is 10th from left. S is 12th from right, so S from left = $N-12+1= N-11$.
2. After swapping, R goes to S's place and becomes 14th from left: $N-11=14$.
3. Solve: $N=14+11=25$.
4. Total students = 25.
