A clock is set right at 5 a.m. The clock loss 16 min in 24 h. What time will be right time when the clock indicate 10 p.m. on the 4th day?

11:00 p.m.

Total number of hours between 5 a.m (First day) to 10 p.m (4th day) = (24 × 3) + 17 = 72 + 17 = 89 Hours

ATQ,

In 24 hours the clock loses 16 minutes

In 01 hours the clock loses \(\frac{16}{24}\) minutes

In 89 hours the clock loses \(\frac{16× 89}{24}\) minutes = 60 min (approx)

Therefore,

The true time of clock, when it shows 10 pm will be: 10 PM + 60 min = 11 p.m on 4th day
