Question: How to print row number from external file based on its first two numbers?


I need to find out how to print the number of row or the numbers on right based only on the combination of the two numbers in first two columns. The external file looks like this:

I have prepared possible combinations of numbers and I need to read the numbers on the right which belongs to this combination. There is no such thing as the sum of two numbers = number of row, so it can't be done this easy.

Can somebody help please? Thanks a lot
