Question

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 1

`1hr=60mins`
`60x3mins` Basically meaning in 20 hours time but then we need include the full hour.
`60x20=1200mins`
`3x20=60mins`
`1200+60=1260` Conversion:
`(1260)/(60) =21hr`
`6pm` on saturday +
`21hr=3pm` on sunday Hope this helps
