- Amit is available at home from 12 noon to 4 p.m. on Tuesday, Thursday and Sunday.
- His younger brother Dermal is available at home on Monday, Thursday, Friday and Sunday between 10 a.m. to 2 p.m.
- The eldest brother Raj is available between 9 a.m. to 12 noon on Monday, Wednesday and Thursday and 2 p.m. to 4 p.m. on Friday, Saturday and Sunday.
At a time, on which day of a week all the three brothers are available at home?
Which of these is a leap year?
How many degrees does a minute hand sweep in 25 minutes?
Radhika is 83 weeks and 6 days older than me, whereas John is 72 weeks and 7 days older than Radhika. If John was born on a Sunday, on which day of the week was I born?
John is 83 + 72 = 155 weeks and 6 + 7 = 13 days older than me. Weeks are in multiples of 7 days. So we can ignore them. We can deal with the 13 days alone. Since 13 = 1 X 7 + 6, the excess days are 6. So we can count the day to Sunday + 6 = Saturday..
If 22nd January of an ordinary, non-leap year falls on a Monday, then what will be the day of week on 26th February of that year?
Count the days from months between January 22 and February 26 like this: January days = 31;Add 26 days of February. Subtract 22 days of January. So total days = 35. Since 35 = 5 X 7 + 0, so excess days are 0. So we can count the day to Monday + 0 = Monday..
