c) default value
d) All of these
48. The default value is specified in a manner syntactically similar to a ________.

c) Actual argument
d) None of these
51. A parameter having a default value in function header becomes ________ in function call.
a) mandatory
b) required
c) optional

52. Default values are considered only when _________ .
a) no value is provided for that parameter in function call.
b) function is not called.
c) function is called with all parameters.
d) None of these
53. In the given code, which argument has default value.
def compoundInterest(principal, rate, time = 5):
ci = p * ( 1 + r/100)**t - p
return cia) principal
b) rate
c) time
d) None of these
54. On the basis of the given code, Identify which of the function call statement is invalid?
def compoundInterest(principal, rate, time = 5):
ci = p * ( 1 + r/100)**t - p
return cia) t = compoundInterest(5000, 10, 15)
b) t = compoundInterest(5000, 15)
c) t = compoundInterest(5000)
d) None of these
55. Why the given function definition is not valid?.
def compoundInterest(principal, rate = 10, time):
ci = p * ( 1 + r/100)**t - p
return cia) because non-default arguments follow the default argument.
b) because the value of variable rate is not valid.
c) because the use of return statement is invalid.
d) None of these

d) def sum(p = 5, q = 10, r ) :
58. Find the output of given code:
def func(x , y = 5, z = 10):
x = y + z
return x + z
print( func(10), func(10, 15), func(10, 15, 25))a) 15 25 35
