Answer:
Explanation:
Let the income per month be S
Total income in 8 months = 8 S .
Total expenses in four months = 2500 x 4 = 10000
Total expenses in next four months = 1750 x 4 = 7000 
Total expenses = 17000 
According to question 
Total income in 8 months = Total expenses 
 8 S = 17000 
S = 2125 per month .
