Question

Rajeev and Sanjeev are too close friends Rajeev's watch gains 1 minute in an hour and Sanjeev's watch loses 2 minutes in an hour. Once they set both the watches at 12: 00 noon, with my correct watch. When will the two incorrect watches of Rajeev and Sanjeev show the same time together?
  1. 8 days later
  2. 10 days later
  3. 6 days later
  4. Can't be determined


Solution

The correct option is B 10 days later
To show the same time together, the difference between two watches must be 12 h.
Now, since they create 3 min difference in 1 h
So they will create 12 h difference in 13×12×6024
= 10 days later
