Detailed Solution
Download Solution PDFGiven:
Boy X's position = 22nd from the left.
Boy Y's position = 33rd from the right.
Total persons (n) = (Rank from Left) + (Rank from Right) - 1
X is 22nd from the left.
Z is 3rd to the right of X.
Z's rank from the left = X's rank from left + 3
= 22 + 3
= 25th.
Next, let's find Boy Z's rank from the right end:
Y is 33rd from the right.
Z is 6th to the left of Y (meaning Z is further away from the left end than Y, when counting from the right end).
Z's rank from the right = Y's rank from right + 6
= 33 + 6
= 39th.
Now we have Z's position from both ends:
Z's rank from left = 25th
Z's rank from right = 39th
n = Z's rank from left + Z's rank from right - 1
= 25 + 39 - 1
= 64 - 1
= 63.
Hence, the correct answer is "Option 4".
