In a row of students, Ankit is 26th from the left end. Poonam is 18 ranks to the right of Ankit. If Poonam is 32nd from the right end, then what will be the rank of Ankit from the right end?
- A52
- B51
- C76
- D50
Solution & Step-by-step Explanation
Let us determine the positions step-by-step:
Ankit's position from the left end = 26
Poonam is 18 ranks to the right of Ankit.
Therefore, Poonam's position from the left end = 26+18=44
We are given that Poonam is 32nd from the right end.
Total number of students in the row = (Position from Left)+(Position from Right)−1
Total=44+32−1=75
Now, we calculate Ankit's rank from the right end:
Ankit’s Rank from Right=Total−(Ankit’s Rank from Left)+1
Ankit’s Rank from Right=75−26+1=50
Thus, Ankit is 50th from the right end.
Ankit's position from the left end = 26
Poonam is 18 ranks to the right of Ankit.
Therefore, Poonam's position from the left end = 26+18=44
We are given that Poonam is 32nd from the right end.
Total number of students in the row = (Position from Left)+(Position from Right)−1
Total=44+32−1=75
Now, we calculate Ankit's rank from the right end:
Ankit’s Rank from Right=Total−(Ankit’s Rank from Left)+1
Ankit’s Rank from Right=75−26+1=50
Thus, Ankit is 50th from the right end.
