In a row of girls, Meena is ninth from the left and Reena is nineteenth from the right. If they interchanges their positions, Meena becomes sixteenth from the left. How many girls are there in the row?

A) 34     

B)        33

C) 29                       

D)        25

E) None of these

Correct Answer: A

Solution :

Explanation: Answer (a) is correct. Total number of girls Since Meena and Reena interchange position, so Meena's new position is the same as Reena's earlier position. This position is 16th from the left (Meena's new position) and 19th from the right (Reena's earlier position). Total = \[\text{L}+\text{R}-1\] Total = \[16+19-1\] Total =\[35-1=34\]. Hence, total number of girls in the row is 34. Rest of the options is incorrect because of the correctness of option (a).
