Question

a clock was set to 6 am on sunday morning. if it loses 15 min in day. what is the actual time when the clock indicates 10 o'clock on wednesday morning?

Answer 1

Answer:

the answer is 9:15 am of Wednesday morning

Answer 2

Answer :-

→ Total time between sunday 6AM to wednesday 10PM = 24 + 24 + 24 + 4 = 76 hours .

now,

→ clock loses in 24 hours = 15 min.

so,

→ 24 hours of correct clock = 24 - 15 = 23 hours 45 minutes of given clock = 23(45/60) = 23(3/4) = (95/4) hours.

then,

→ (95/4) hours of this clock = 24 hours of correct clock .

→ 76 hours of this clock = 24 * (4/95) * 76 ≈ 76.8 hours.

therefore,

→ Clock loses = 76.8 - 76 = 0.8 hours = 0.8 * 60 = 48 minutes .

hence,

→ Exact time = 10AM + 48 minutes = 10:48 AM (Ans.)
