#### Clock and calender

1. If January 1 is a Friday, what is the first day of the month of March in a leap year?

1. Total number of days from January 1 to march 1
= 31 + 29 + 1
= 61 days
(February in leap years = 29 days) = 61 ÷ 7
= 8 weeks and 5 odd days

##### Correct Option: A

Total number of days from January 1 to march 1
= 31 + 29 + 1
= 61 days
(February in leap years = 29 days) = 61 ÷ 7
= 8 weeks and 5 odd days
So, the fifth day from Friday = Tuesday

1. A bus for Delhi leaves every 30 minutes from a bus stand. An inquiry clerk told a passenger that the bus had already left 10 min ago and next bus will leave at 9 : 35 am. At what time did the inquiry clerk give this information to the passenger?

1. Next bus will leave at 9 : 35 am. So, last bus left at (9 : 35 - 0 : 30) = 9 : 05 am

##### Correct Option: D

Next bus will leave at 9 : 35 am. So, last bus left at (9 : 35 - 0 : 30) = 9 : 50 am
So, inquiry clerk gave the information to the passenger at = (9 : 05 + 0 : 10)
= 9 : 15 am

So, the next Tuesday will come on the Mrs Susheela's wedding anniversary in 30th September, 2003

1. The day before the day before yesterday is three days after Saturday. What day is it today?

1. Find the angle between minute hand and hour hand at 4 : 20 Am

1. At 4 : 20 A.M. from the formula here P = 4 and Q = 20 so required angle is 11 x 20/2 - 30 x 4 = 110 - 120 = - 10 or ignoring the negative sign the required angle is 10°

##### Correct Option: A

At 4 : 20 A.M. from the formula here P = 4 and Q = 20 so required angle is 11 x 20/2 - 30 x 4 = 110 - 120 = - 10 or ignoring the negative sign the required angle is 10°

1. Find the angle between minute hand and hour hand at 1 : 40 AM

1. At 1 : 40 from the formula here P = 1 and Q = 40 so required angle is 11 x 40/2 - 30 x 1 = 220 - 30 = 190 the required angle is 190°

##### Correct Option: B

At 1 : 40 from the formula here P = 1 and Q = 40 so required angle is 11 x 40/2 - 30 x 1 = 220 - 30 = 190 the required angle is 190°
