def mutate_dict(d):
    d['a'] = 20
    d['c'] = 40
    
d1 = {'a': 10, 'b': 20}
d2 = d1
d2['b'] = 30
mutate_dict(d1)
print(d2['a'] + d1['b'])
  1. $60$
     
  2. $50$

This question tests the understanding of mutable objects (dictionaries) and variable referencing in Python. Dictionaries are mutable, and assignments like $\verb|d2 = d1|$ create a shared reference.

$\verb|d2['a']|$ is $20.$

$\verb|d1['b']|$ is $30.$

Result: $20+30=50$.
