Logical Sequence of Time
Logical Sequence of Time
Logical Sequence Of Time: Sequence simply implies arrangement of occurrence of events in accordance to the passage of time. That is to say, that which event occurs at what time followed and preceded by which events and at what times and so on so forth. To solve such problems, a base time is convenient in accordance to the conditions specified in the questions. The times of occurrence of all other events are measured in reference to the base time. The key to solving these questions is to use common sense and overall logical reasoning. All this, of course, is better explained by the use of examples which are given below.
Illustration: A bus for Delhi leaves after every thirty minutes. An enquiry clerk told a passenger that the bus had already left ten minutes ago and the next bus would leave at 9:35 a.m. At what time did the enquiry clerk give this information to the passenger?
A. 9:10 a.m. B. 8:55 a.m. C. 9:05 a.m. D. 9:15 a.m.
Answer: D
Sol. The next bus will leave at 9:35 a.m. As this is the only concrete time given in the question, let this be the base time. This means that the previous bus had left at 9:05 a.m. But it happened ten minutes before the clerk gave the information to the passenger. Thus, the enquiry clerk gave the information at 9: 15 a.m.
Hence, the correct choice is (4).
Illustration: At 8 p.m. on Thursday. Kiran's watch was slow by 5 minutes. But at 8 a.m. on Sunday. it was fast by 10 minutes. At what time did it give the right time?
A. 8 p.m. on Saturday B. 4 p.m. on Friday C. 12 noon on Saturday D. 12 a.m. on Friday
Answer: B
Solution: From 8 p.m. on Thursday to 8 a.m. on Sunday, there are 2 complete days and one half day, i.e. 2 X 24 + 12 = 60 hours gap, and the watch gains (5 + 10) 15 minutes. In the time the non defective clock registers a time span of 60 hours,
So 15 minutes are gained in 60 hours
or 1 minute is gained in 60/15 = 4 hours
or 5 minutes are gained in = 4 X 5 = 20 hours
Let the base time be 8pm on Thursday and adding 20 hours we will get 4pm on Friday
Thus, the correct time will be on 4:00 p.m. on Friday. Hence, answer option B is correct.
