In a queue of 117 persons, if Asif's position from the beginning is 50, what is his position from the end?
Explanation
Step 1: Note down the given details
Total strength of the line:
Total=117
Asif's rank from the start or beginning:
Position from beginning=50
Step 2: Use the standard ranking formula
The relationship between the total number of items/people in a linear row and an individual's positions from both extremes is given by:
Total=(Position from Beginning)+(Position from End)−1
To find the position from the end, rewrite the equation:
Position from End=Total−Position from Beginning+1
Step 3: Perform the final calculation
Substitute the given values into the formula:
Position from End=117−50+1
Position from End=67+1=68
Final Answer
Asif is standing at the 68th spot when counting from the rear of the queue.
Correct Option: (b) 68
