16. Give the output of the following when num1 = 4,num2 = 3, num3 = 2
a) num1 += num2 + num3
print (num1)
b) num1 = num1 ** (num2 + num3)
print (num1)
c) num1 **= num2 + num3
d) num1 = '5' + '5'
print(num1)
e) print(4.00/(2.0+2.0))
f) num1 = 2+9*((3*12)-8)/10
print(num1)
g) num1 = 24 // 4 // 2
print(num1)
h) num1 = float(10)
print (num1)
i) num1 = int('3.14')
print (num1)
j) print('Bye' == 'BYE')
k) print(10 != 9 and 20 >= 20)
l) print(10 + 6 * 2 ** 2 != 9//4 -3 and 29>= 29/9)
m) print(5 % 10 + 10 < 50 and 29 <= 29)
n) print((0 < 6) or (not(10 == 6) and(10<0)))

20. Write a Python program to calculate the amountpayable if money has been lent on simple
interest.Principal or money lent = P, Rate of interest = R%per annum and Time = T years.
Then Simple Interest(SI) = (P x R x T)/ 100.
Amount payable = Principal + SI.
P, R and T are given as input to the program.
