Consider a group comprising of 4 students: Reena, Beena, Meena and Neena, who stand in a row. Reena and Beena stand in 6th and 7th positions respectively from the left. Meena and Neena stand in the 4th and 5th positions respectively from the right. When Beena and Meena exchange their positions, then Beena will be 15th from the left.

Your Answer : (Not Answered) Correct Answer :

14

Explanation :

Positions as given
1L,2L,3L,4L,5L,Reena(6L), Beena(7L) ... Neena(5R),Meena(4R),3R,2R,1R

After Beena and Meena exchange their positions
1L,2L,3L,4L,5L,Reena(6L), Meena(7L),8L,9L,10L,11L,12L,13L,Neena(14R),Beena(15L),3R,2R,1R
