Two watches, one of which gained at the rate of 1 min. and the other lost at the rate of 1 min. daily, were set correctly at noon on the 1st Jan., 1987. When did the watches indicate the same time?
Dec. 27, 1987 mid-night.
Dec. 27, 1987 noon.
Dec. 28, 1987 noon.
Dec. 24, 1987 noon.
The first watch gains on the second watch 1 + 1 =2 min. in a day. The watches will indicate same time when one has gained 12 hours on the second. As 2 minutes are gained in 1 day. So 12 hours are gained in = 1⁄2 x 12 x 60 = 360 days. Counting 360 days from 1st Jan. 1987 we get Dec. 27, 1987.
