Answer 1

Answer:

Correct Option: A

We know that ,

Time from 5 pm Tuesday to 11 pm Wednesday = 30 hours

Clock gains 8 minutes in 30 hours

∴ It gains 3 minutes in 30 x 3 hours = 11 hours 15 minutes.

8

∴ Correct time is 11 hours 15 minutes after 5 pm. = 4 : 15 am on Wednesday.

Thus , required correct time is 4 : 15 am on Wednesday

Answer 2

on Wednesday 4:15 a.m the clock will give correct time
