Automatically add multiple original field entries total (that has multiple entries)

Hi All,

What I have is a spreadsheet of cities (there are multiple cities that are the same) - and they have a # of receives column too. What I want is to be able to add up all the cities #of receives that are the same City. for instance Dehli has over 50 lines of # of receives and instead of manually scrolling down and adding each cell together with a formula, I thought there would be an easier way to do this;

SPreadsheet attached.

Thanks for all your help!

Thank you kindly !
