Clock Reasoning Questions – Easy Level

Q-36. By looking in a mirror it appears that it is 6 : 30 in the clock. What is the real time?
(a) 6:30
(b) 5:30
(c) 6:00
(d) 5:00

View Answer and Solution 

Answer: (b) 5:30
Solution:
Because the time 6 : 30 lies between 1 : 00 to 11 : 00, hence we substruct that time from 11 : 60
11:60-6:30 = 5:30
 

Q-37. A clock only with only dots marking 3, 6, 9 and 12 positions has been kept upside down in front of mirror. A person reads the time in the reflection of the clock as 4.50. What is the actual time?
(a) 08 : 10 (b) 01 : 40
(c ) 04:50 (d) 10 : 20

View Answer and Solution 

Answer: (b) 01 : 40
Solution:
Here the reflection works as a water image.

In this time 4 : 50 the hour hand is between 12 : 00 to 6 : 00 and the minute hand is between 6 : 00 to 12 : 00 clockwise. Hence we subtract that time from 5 : 90
5:90 - 4:50 = 1:40
 

Q-38. A clock only with dots marking 3, 6, 9, and 12 O’clock positions has been kept upside down in front of a mirror. A person reads the time in the reflection of the clock as 10:20. What is the actual time?
(a) 07: 10 (b) 02 : 40
(c) 04:50 (d) 10 : 20

View Answer and Solution 

Answer: (a) 07: 10
Solution:
Here the reflection works as a water image

In this time 10: 20, the hour hand is between 6:00 to 12 : 00 and the minute hand is between 12 : 00 to 6 : 00 clockwise. Hence we subtract that time from 17:30
17:30 - 10: 20 = 7: 10
 

Q-39. A clock goes slow from midnight by 5 min. at the end of the first hour, by 10 min. at the end of the second hour, by 15 min. and the end of the 3rd hour and so on. What will be the time by this clock after 6 hours?
(a) 6:00am (b) 5:30am
(c) 6:30am (d) 5:15am

View Answer and Solution 

Answer: (b) 5:30am

It goes a low In 1 hour = 5 mts
then in 6 hour = 5 × 6 = 30 minutes
Then after 6 hour the time will be = 5:30 a.m.

Q-40. A clock goes fast by one minute during the first hour, by two minutes at the end of the second hour, by 4 minutes at the end of 3rd hour, by eight minutes by the end of 4th hour, and so on. At the end of which hour, will it be fast by just over sixty minutes?
(a) Fifth (b) Sixth
(c) Seventh (d) Eighth

View Answer and Solution 

Answer: (c) Seventh
Solution:
Every hour it is double fast of given minutes
(2x times difference)
In 8 minute fast = In 4th hour
16 minute fast = In 5th hour
32 minute fast = In 6th hour
64 minute fast = In 7th hour
64 minute is just over 60 minutes
