Correct Answer: 25


Solution : Given:
Anvita charged INR 9 for a call.
If INR 2 is charged for the first 5 minutes, then after 5 minutes charges are = 9 – 2 = 7
Charges per minute call = 35 paise
Thus, minutes for the call after 5 minutes –
Remaining charges ÷ Charges per minute after 5 minutes = 7 ÷ 0.35 = 20

So, the total duration of a call is 20 + 5 = 25 minutes. Hence, the fourth option is correct.
