Question 7

March 5, 1999 was on Friday. What day of the week was on March 5, 2000?

Accepted Answer

As per the given above question , we know that Year 2000 was a leap year. Number of days remaining in 1999 = 365 - [31 days of January + 28 days of February + 5 days March] = 301 days = 43 weeks, i.e., 0 odd day. Number of days passed in 2000 = January 31 days have 3 odd days. February 29 days (being leap year) have 1 odd day March 5 days have 5 odd days. ∴ Total number of odd days = 0 + 3 + 1 + 5 = 9 days = 1 week + 2 odd days Therefore, March 5, 2000 would be two days beyond Friday, i.e., on Sunday.

Question 8

The first Republic Day of India was celebrated on January 26, 1950. What was the day of the week on that date?

Accepted Answer

According to question , we can say that Total number of odd days = 1600 years have 0 odd day + 300 years have 1 odd day + 49 years (12 leap years + 37 ordinary years) have 5 odd days + 26 days of January have 5 odd days = 0 + 1 + 5 + 5 = 4 odd days. So, the day was Thursday.

Question 9

If the day after tomorrow is Sunday, what day was tomorrow's day before yesterday?

Accepted Answer

Given that , The day after tomorrow is Sunday. Therefore today is Friday. Hence, the day on tomorrow's day before yesterday is given by: = Friday – 1 day = Thursday Therefore , required day will be Thursday .

Question 10

In every 30 minutes the time of a watch increases by 3 minutes. After setting the correct time at 5 am what time will the watch show after 6 hours?

Accepted Answer

We know that , In every 30 minutes the time of watch increased by 3 minutes = 12 × 3 = 36 minutes So the time after 6 hours = 5 am + 6 hours + 30 minutes = 11 : 36 am. Therefore , required time will be 11 : 36 am.

Question 11

Reaching the place of meeting on Tuesday 15 min before 8:30 h, Anuj found himself half an hour earlier than the man who was 40 min late. What was the scheduled time of the meeting?

Number of buzzes in a day = 12(12 + 1)/2 x 2 = 156

Question 13

How many times are the hands of a clock is at right angle in a day?

Accepted Answer

In 12 h, they are at a right angles, 22 times. So, in 24 h, they are at right angles, 44 times.

Question 14

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

Accepted Answer

From the properties of the clock, we know that hands of a clock coincide once in every hour but between 11 O'clock and 1 O'clock, they coincide only once. Therefore, the hands of a clock coincide 11 time in every 12 h. Hence, they will coincide (11 x 2) = 22 times in 24 h. 89 h of this clock = 90 h of correct clock Therefore, it is clear that in 89 h this clock losses 1 h and hence, the correct time is 11 : 00 pm when this clock shown 10 : 00 pm.

Question 15

How many times do the hands of a clock points towards each other in a day?

Accepted Answer

The hands of a clock point towards each other 11 times in every 12 h (because between 5 and 7, they point towards each other only once at 6 O'clock). Therefore, in a day, the hands points 22 times in all, towards each other.
