In a row of girls, Veena is 12th from the start and 19th from the end. In another row of girls. Sunita is 14th from the start and 20th from the end. How many girls are there in both the rows together?

In first row, Veena is 12th from start and 19th from end.
Then total number of girls = (12 + 19 - 1) = 30
In second row, Sunita is 14th from start and 20th form the end.
Then, total number of girls = (14 + 20 - 1) = 33
∴ Total number of girls = 30 + 33 = 63
