Correct option is A
Given:
- In a row where all are facing north, Priya is 15th from the left end and Garima is 19th from the right end.
- They interchange their positions and Ram, who sits 24th from the left end sits at the 5th place to the left of Priya's new position.
According to given information:
After new condition:
Total person = Before person of Garima + 8 person + Ram + 4 person + Priya + After person of priya
Total person = 14 + 1 + 8 + 1 + 4 + 1 + 18
Total person = 47 person
So, total 47 persons are there in the row.
Thus, the correct answer is (a).
