In a row of 49 students facing north, Ankur is 19th from the right end. If Tinu is 11th to the left of Ankur, what is Tinu's position from the left end of the line?

Correct option is C

Given:
In a row of 49 students facing north, Ankur is 19th from the right end. Tinu is 11th to the left of Ankur.

Explanation (applied left to right):

Ankur's position from the right end:
Ankur is 19th from the right end, so his position from the left end will be:
49 - 19 + 1 = 31st from the left end.

Tinu's position relative to Ankur:
Tinu is 11th to the left of Ankur. So, Tinu's position from the left end will be:
31 - 11 = 20th from the left end.

Final Answer:
20
