Answer 2

Hey Friend Here's Your Answer

According to Her Monthly Plan, She pays ₹145/month.
And for 1 extra Minute, She has to pay ₹0.75

Her Bill Was : ₹178

But She has to pay ₹145 as plan!

So Money For which she paid, I.e Extra talked:

₹178-₹145
=₹33

Now, for 1 minute, She pays ₹0.75

For 60 seconds, She pays 0.75 ₹ ( 1minute =60s)

Therefore, When we divide 33/0.75,

We Get 44 minutes

Hence She Talked 44 Minutes Beyond The Extended Time!

Hope This Helps......!!!!
Thanks!
