Question : Directions: In a row of people all facing north, Prince is 5th from the right end. Amit is 15th from the right end. Amit is exactly between Prince and Aditya. If Aditya is sixth from the left end of the line, how many people are there in the row?
Option 1: 29
Option 2: 31
Option 3: 30
Option 4: 32
Correct Answer: 30
Solution :
Given:
Prince is 5th from the right end.
Amit is 15th from the right end.
Amit is exactly between Prince and Aditya.
Aditya is sixth from the left end of the line.
→The number of people between Amit and Prince = (Position of Amit from right – Position of Prince from right) – 1
= 15 – 5 – 1 = 9
Thus, the number of people between Amit and Aditya = 9
→The position of Aditya from right = Position of Amit from right + 9 + 1
= 15 + 9 + 1 = 25
→The position of Aditya from right = 25
Total number of people = Position of Aditya from right + Position of Aditya from left – 1
= 25 + 6 – 1
= 30
So, there are a total of 30 people in the row. Hence, the third option is correct.
