A Digital clock is gaining three minutes every hour.If you set it to the correct time at 6pm on Saturday,when will it show the correct time again ?



Answer :

[tex]1hr=60mins[/tex] [tex]60x3mins[/tex] Basically meaning in 20 hours time but then we need include the full hour. [tex]60x20=1200mins[/tex] [tex]3x20=60mins[/tex] [tex]1200+60=1260[/tex] Conversion: [tex] \frac{1260}{60} =21hr[/tex] [tex]6pm[/tex] on saturday + [tex]21hr=3pm[/tex] on sunday Hope this helps
