使用 excel 查找范围数据的 Vlookup

Question

I have two excel files, I want to perform vlookup and find difference of costs using excel.

My files look like this

source_data.xlsx contains contains distance covered and their price, example distance range from 1 to 100 should be charged 4800 and distance range from 101 to 120 should be charged 5100.

DISTANCE     COST    
1-100        4800
101-120      5100    
121-140      5500    
141-160      5900    
161-180      6200    
181-200      6600    
210-220      6900   
221-240      7200

KIGOMA                77                1000       PAID    
KIGOMA                90                4000       PAID

Actual Cost for distance is given in source_data.xlsx, I want to check cost in Analysis.xlsx if it correspond to Actual value, I want to detect underpayment and overpayment.

Desired Output should be like this, with two column added, source_cost which is taken from source_xlsx by using vlookup and difference which is difference between total_cost and source_cost

loading_station distance_travel total_cost  status  source_cost Difference

Answer 1

Try this:

Vlookup(B40,$A$2:$B$8,2,1)

This assumes the distance/cost is in the table A2:B8, and the first cost to be found based on distance given is in B40.

But why do you get a result of 4000 for a distance of 40, when your table of distance/cost (analysis) shows anything 1 to 100 is 4800?
