The given table shows the average number of pies ‘A’ and ‘B’, ratio of number of pipe ‘A’ to that of pipe ‘C’ and difference between number of pipes ‘B’ and ‘C’, at the respective sites.Sites	Average number of pipes ‘A’ and ‘B’	Ratio of number of pipe ‘A’ to that of pipe ‘C’	Difference between number of pipes ‘B’ and ‘C.
1	110	1 : 2	140
2	225	2 : 1	150
3	230	4 : 5	100
4	180	4 : 5	180
