Consider a watch becomes fast by 10 minutes every day. By what percent does it become fast?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → \(\frac{25}{36}\)%
The watch gains 10 minutes in every day of correct time, so the gain is taken as a percentage of the minutes in one day.
One day \(=24\times60=1440\) minutes
Gain \(\displaystyle =\frac{10}{1440}\times100=\frac{1000}{1440}=\frac{25}{36}\%\)
