If Reshma is 3rd from the right end and Neelam is 2nd from the left end and 5 girls are between them, then number of girls in the row is _________.

A10
B12
C9
D8


When ever there is a gender based question, Please put the correct pro-nouns . We should not always assume that Reshma and Neelam are girls . ( e.g: Kiran can be a boy name as well as girl name) . So your question should be how many students/kids/persons in the row . Please understand IMO is also attended by International school students , not only Indian students.
