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: $\frac{1260}{60} =21hr$ $6pm$ on saturday + $21hr=3pm$ on sunday Hope this helps
