Answer:
40000
Step-by-step explanation:
Simple interest (I) is calculated as
I = 
P is the amount borrowed , R is the interest and T the time in years
Here I = 2000 , R = 5 and T = 1 with P to be found , then
2000 =  ( multiply both sides by 100 )
 ( multiply both sides by 100 )
5P = 200000 ( divide both sides by 5 )
P = 40000
