Answer 1

⊕ Question:-

A watch is getting slow by 3 minutes for each hour  in a day. If it shows 8 a.m. now, what will be the  time after 10 hours in the watch?

⊕ Answer:-

As the watch is getting 3mins slower per hour, = 3 × 10

                                                                               = 30 mins

With respect to 8 a.m., after 10 hours the time would be 6 p.m.

Subtracting 30 mins from 6 p.m.,

the time will be 5:30 p.m.

∴ The time after 10 hours in the watch will be 5:30 p.m.
