Challenge time..! Please come here fast, so that I can post the question...! @mathslover @ParthKohli @Kemist @aajugdar @ganeshie8 @megprowder

OpenStudy (gudden):

here you go with the question... You people got exactly three minutes to do it... and your time starts now.. A clock is set right I p.m. If it gains one minute in an hour, what is the true time when the clock indicates 6 p/m. the same day.

OpenStudy (anonymous):

6:05?

OpenStudy (anonymous):

pm

OpenStudy (anonymous):

5:56

OpenStudy (gudden):

@aajugdar .. please be precise... and @Kemist ...NO....

OpenStudy (anonymous):

1:05pm*

OpenStudy (gudden):

Exactly 1 min left....

OpenStudy (anonymous):

well if you start from 1 pm when its 2 pm it will show 2.01 .... at 5 pm...5:04 so when its showing 6 its 4 mins behind thats 5:56

OpenStudy (gudden):

Time UP....

OpenStudy (anonymous):

Omg. no way. 6:03 pm

OpenStudy (anonymous):

I call bs.

OpenStudy (gudden):

Well.. The answer most close was that of @aajugdar .... And the actual answer is 5 : 55.08 PM...XD

OpenStudy (anonymous):

._. I don't get it.

OpenStudy (anonymous):

hah :P

OpenStudy (gudden):

Show your work @Kemist ...

OpenStudy (gudden):

Let me show my work... True time interval/Time interval in incorrect clock = 1/1+ hour gained in 1 hour by the incorrect clock => True time interval/5 = 1/1+1/60 Solving it true time interval comes out to be 300/61 hours... and hence true time = 1 pm + 4 *56/61 hours.. => 55*5/61 minutes past 5 pm...:)

OpenStudy (anonymous):

wow i could've never solved like that :P

OpenStudy (anonymous):

That's too much work for me.

OpenStudy (gudden):

Hhahah.. @Kemist ... And @aajugdar .. well your method was correct too..! But it wouldn't have worked out if I had given options with a minor difference..!

OpenStudy (anonymous):

maybe i'd hv calculated the increase rate per minute :P but then again i had only 3 mins xD

OpenStudy (gudden):

LOL.. I don't think it even consumed like a minute...! I took a while to write.. otherwise calculations were easy..^_^

OpenStudy (anonymous):

yep indeed:P

OpenStudy (gudden):

@ParthKohli... was the question too easy for you , that you even didn't bother to answer it... :P

mathslover (mathslover):

OpenStudy (anonymous):
