Answer 2

Sushant slept for  8 hours 20 minutes.

Step-by-step explanation:

12 at midnight is same as 0 am.

Calculating the time from 10 : 30 pm to 12 at midnight or 0 am,

we subtract, 10 : 30 pm from 12 am,

12 : 00 - 10 : 30 = 1 : 30-------that is 1 hour 30 minutes.

Calculating the time from 0 am and 6 : 50 am,

we subtract, 0 pm from 6 : 50 am,

6 : 50 - 00 : 00 = 6 : 50-------that is 6 hours 50 minutes.

Total time =  6 hours 50 minutes + 1 hours 30 minutes

that is, 7 hours 80 minutes,

but, 1 hour is 60 minutes , so,

7 hours 80 minutes, can be represented as 7 hours + 60 minutes + 20 minutes,

that is, 7 hours + 1 hour + 20 minutes,

that is, 8 hours + 20 minutes,

that is, 8 hours 20 minutes.

Sushant slept for  8 hours 20 minutes.
