When Ankita called Dipanjan in the evening, it was four times as many minutes past 4 pm as it was to 6 pm. When they hung up, it was twice as many minutes past 5 pm as it was to 7 pm. For how long did they talk?
Between 4 pm and 6 pm it is taken that 5x=120. And the time comes out to be 5:36pm.Can smby explain why 5x=120 is der?
