Question

a watch is a minute slow at 1pm on Wednesday and 2 mins fast at 1pm on friday when dif it show tje right time​

Answer 1

Wednesday at 1pm:

The watch is a minute slow(-1 minute)

On Friday at 1pm:

The watch is 2 minutes ahead(+2 minutes)

Difference between them=[(-1)-(+2)]=|-3|

=3 minutes

The watch needs to overspeed for 1 minute to cancel any difference between the actual time and time on the watch.

Therefore;

3 minutes:48 hours

1 minute:x hours

x=(1*48)/3=16 hours

So I think the answer is after 16 hours from that time onwards which will be 5 am(for 12-hour watch)

Let me know if the answer is wrong
