Question
In a row of persons, the position of A from the left side of the row is 9th & the position of B from the right side of the row is 8th. If C is sitting just in the middle of A & B and the position of C from the left side of the row is 15th. Find the total no. of persons in the row?a.28b.30c.29d.27
Solution
The problem states that A is 9th from the left, B is 8th from the right, and C is in the middle of A and B, being 15th from the left.
To find the total number of people in the row, we need to find the position of B from the left. Since C is in the middle of A and B, and C is 15th from the left, B must be 15 + (15 - 9) = 21st from the left.
Since B is also 8th from the right, the total number of people in the row is 21 + 8 - 1 = 28.
So, the answer is a. 28.
