A) 18th                              

B) 19th

C) 20th                              

D) 17th

Correct Answer: A

Solution :

Shortcut: Total students (50) = Rita's position from start (10) + Sheetal's position from end (25) + Middle persons(x). 50 = 10 + 25 + x \[\Rightarrow \] 50 = 35 + x \[\Rightarrow \]15 = x Tara's position from start = Rita's position from start (10) + Tara's position from Rita (8). =   10 + 8 \[\Rightarrow \]18 Hence, Tara's position from start = 18th
