Given that there are 40 children in a row.
Panoo is 13th from the left end, so Panoo's position from left = 13
Qanoo is 9th from the right end.
Position from left = Total children - Position from right + 1
Qanoo's position from left = 40 - 9 + 1
Qanoo's position from left = 32
Ranoo is fourth to the left of Qanoo.
Ranoo's position from left = 32 - 4
Ranoo's position from left = 28
Number of children between Panoo and Ranoo:
Panoo is at position 13
Ranoo is at position 28
Children between them = 28 - 13 - 1
Children between them = 14
Therefore, there are 14 children between Panoo and Ranoo.
