In a row of 40 students facing North, Kailash is 6th of the left of Soman. If Soman is 30th from the left end of the row, how far is Kailash from the right end of the row?
Answer & explanation
Correct answer: option 1
Total = 40
Soman is 30th from the left
therefore, Kailash is 24th from left (30 - 6 = 24)
T = Left Rank + Right Rank - 1
40 = 24 + R - 1
R = 17
