Hey mate thank for the question
Hope it helps
In this type of question we use Arithmetic Progressions (AP)
Income of doctor becomes the first term .ie.,,,(a)=22100
Increase in income become the common difference (d)=490
No of months (n)=4
So Total Amount =Fourth term of AP
Total amount=a+(n-1)d
Total amount=22100+(4-1)×490
Total amount =22100+3×490
Total amount=22100+1470
Total amount=23570
