To Find : what is the exact time now?
सध्या ची अचूक वेळ कोणती?
Solution:
2 o'clock in clock
6 o'clock in clock
Hence clock has shown 4 hours
clock goes back 30 minutes every hour
=> Clock shows 1hr in 2 hr
Clock showed 4 hr in 8hrs
2 o'clock + 8hrs
= 10 o'clock was the time when clock stopped
it has been 3 hrs when clock stopped
= 10 o'clock + 3 hr
= 13 o'clock
= 1 o'clock
