Hi Geeks

SQL

Combo  Sizes   Ratio
  1     56       1
  1     62       2
  1     68       2
  1     74       1 
  1     80       1
  2     62       1
  2     68       2
  2     74       2
  2     80       1

I've a checkbox which shows 1&2 in UI. When I select both 1 and 2, I should get result like this

SQL

Sizes   Ratio
 56       1
 62       3
 68       4
 74       4
 80       2

which should add the ratio according to the sizes. I stuck up with logic. Can anyone help me with this logic?
