In a row of persons facing north, Deepti is 15th from the left end and Mahima is 19th from the right end. They interchange their positions. Shyam, who is 24th from the left end, is now 5th to the left of Deepti. How many persons are there in the row?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 47
After the interchange Deepti stands in Mahima’s old place, 19th from the right. Shyam gives the same place counted from the left.
Shyam is 5th to the left of Deepti, so Deepti is 5th to the right of Shyam
Deepti from the left \(=24+5=29\)th
Deepti from the right: 19th (Mahima’s old place)
Persons in the row \(=29+19-1=47\)
