answer is OK but please discuss step by step
I don't know about this
As it is given in the question that clock runs 5min. Fast per hour this means 5min. Are added in every hour
And by adding the 5min. The time from 12noon is 6:30 pm
So now to find the correct answer 5 min. Would be subracted from evry hour
From 12noon to 6:30 pmm total are 6 hours 30 min.
Now subract 5min from each hour and 6×5 =30 min. ... so when you subract 5 min. From each hour that is total of 6 hour the answer will be 30min. Of total will be subracted ...
Hope it helps you

Answer:
Step-by-step explanation:
6hr 30 mins = 390 mins
As the clock runs 5 mins fast in an hour
So, when 65 mins is crazy time the actual time is 60 mins
when 390 mins is crazy time the actual time is (390x 60/65)mins =360mins
i. e. 360 mins = 6 hours
12pm + 6 hr = 6:00 pm
Ans is 6:00pm
