You can solve this question as
Total bill paid = 120 = 99+ 21
Now, By Unitary method we will calculate the no. of calls in Rs 21.
In 50 rupees, 60 sec. call.
In 21 rupees,
(60/50 )*21= 126/5 sec.
total voice calls = 2000 min 126/5 sec.
Total bill paid = 120 = 99+ 21
Now, By Unitary method we will calculate the no. of calls in Rs 21.
In 50 rupees, 60 sec. call.
In 21 rupees,
