In a row of girls, Ranya is 15th from left and Tanya is 19th from right. If Ranya is 19th from right, what is the position of Tanya from left?
Explanation:
Total number of people = position of a person from the left + position of the same person from right – 1.
If the position of A from left and right is known, and the position of B from any one end is known, the position of B from the other end can also be found.
∴ Ranya’s position from left + Ranya’s position from right = Tanya’s position from left + Tanya’s position from right
∴ 15 + 19 = Tanya’s position from left + 19
∴ Position of Tanya from left = 15th
Hence, option (c).
