How many times do the hands of a clock coincide in 5 hours ?

A. 5

B. 4

C. 6

D. 3

Answer : B. 4

Explanation:

Hour hand and minute hand coincide every 65:5 minute, so in 5 hour they will coincide 4 times The hour hand covers 2*360 degrees in 24 hours, i.e 1440 minutes. So, in one minute, it covers 1440/720 = 1/2 degree.

Difference in angular distance travelled by the minute hand and the hour hand in one minute is thus 6-1/2 = 11/2 degrees. So, on a full rotation (360ᵒ), any similar event between them will be repeated every 360/(11/2) = 65 5/11 minutes.

The famous church in the city of Kumbakonam has a big clock tower and is said to be over 300 years old. Every Monday 10.00 AM the clock is set by Antony, doing service in the church. The Clock loses 6 minutes every hour. What will be the actual time when the faulty clock shows 3 P.M on Friday ?

A. 1.10 am

B. 1.40 am

C. 12.10 am

D. 12.10 pm

Answer : A. 1.10 am

Explanation:

  • Let us start from Monday 10 am to friday 3.00 pm , total hours = 4 days 5 hrs(4*24+5 = 101 hrs).
  • Clock lose per hour = 6 min, so total time loses is 101 * 6minutes = 606 minutes (10 hrs 10 minutes ).
  • So actual time = Friday 3.00 pm + 10 hrs 10 minutes = saturday 1.10 am.
