Q41 2017, Clocks and Calendars

A watch loses 2 minutes in every 24 hours while another watch gains 2 minutes in every 24 hours. At a particular instant, the two watches showed an identical time. Which of the following statements is correct if 24-hour clock is followed?

एक घड़ी हर 24 घंटे में 2 मिनट धीमी हो जाती है, जबकि एक दूसरी घड़ी हर 24 घंटे में 12 मिनट तेज हो जाती है। एक विशेष क्षण पर दोनों पहिलों एक-ही समय दिखाती हैं। यदि 24 घंटे बातें पहली घड़ी का अनुसरण करें, तो निम्नलिखित कथनों में से कौन-सा सही है?

A watch loses 2 minutes in every 24 hours, while another watch gains 2 minutes in every 24 hours.

Hence, every day the time difference between the two watches will keep on increasing by 4 minutes.

They will again show the same identical time when this difference increases to 24 hours, i.e. 24 × 60 minutes or 1440 minutes.

If 4 minutes are gained per day, then 1440 minutes will be gained in 1440 / 4 = 360 days.
