Given:

The expenditure of IT department in 2015 = 220

The expenditure of IT department in 2016 = 320

The expenditure of IT department in 2017 = 410

The expenditure of IT department in 2018 = 450

The expenditure of operation department in 2015 = 250

The expenditure of operation department in 2016 = 350

The expenditure of operation department in 2017 = 500

The expenditure of operation department in 2018 = 500

Calculation:

⇒ The total expenditure of IT department in all given years = 220 + 320 + 410 + 450 = 1400

⇒ The total expenditure of operation department in all given years = 250 + 350 + 500 + 500 = 1600

⇒ The required ratio = 1400 : 1600 = 7 : 8

∴ The required result will be 7 : 8.
