2. program to find simple interest for given principal amount, time and rate of interest.

  

# We can change values here for
# different inputs

P = int(input())
R = int(input()) 
T = int(input())

# Calculates simple interest 

SI = (P * R * T) / 100

# Print the resultant value of SI 

print("simple interest is", SI)
