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.
