In a row of 15 students facing the north, Yusuf is 10th from the right end. If Suman is 4th to the left of Yusuf, what is Suman's position from the left end of the line?
2nd
There are 15 students in the row, and Yusuf is 10th from the right end.
Yusuf's position from the left end is \(15 - 10 + 1 = 6\), so Yusuf is 6th from the left.
Suman is 4th to the left of Yusuf, so Suman's position from the left end is \(6 - 4 = 2\).
Hence, Suman is 2nd from the left end of the line.
