Question

In a row of girls, Rita and Monika occupy the ninth place from the right end and the tenth place from the left end respectively. If they interchange their places, then Rita and Monika occupy the seventh place from the right and the eighteenth place from the left respectively. How many girls are there in the row?

• A. 25
• B. 26
• C. 27
• D. Data inadequate
• E. None of these

Answer 1

The correct option is B 26

Since Rita and Monika exchange places, Rita's new position is the same as Monika's earlier position. This position is 17th from the right and 10th from the left
$\therefore$ Number of girls in the row =(16+1+9) =26
