1. q = 11/2 m – 30h

= 11/2 *30  - 30 *5

= 165-150 = 150

2. 18*2 *6 = 216  degree

3. The number of hours from 8:00 p.m. on Thursday to 8:00 a.m. on Monday = 84
hours.

In 84 hours, the clock gained 12 minutes.

But to show the correct time, the clock has to gain 5 minutes.

:. 5/12 *84 = 35 hours.

35 hours from 8:00 p.m. on Thursday is 7:00 a.m. on Saturday.

4. 3960/(360*2) = 5.50

5. 42*6-(42/2) = 252-21 = 231 degree

6. Odd days from March to October : 3 + 2 +3 +2 +3 +3 +2 +3 = 21/7 = 0 . If odd day
is 0 then next  month has the same calendar.

7. 730/7 = 2 odd days. So Saturday will be the day of the week.

8. It is a leap year.  So 16(Jan)+ 29(Feb) + 15(March) = 60 days

9. 100 years contains 5 odd days. So last day of 1st century is ‘Friday’.

200 years contains (5*2) =10 = 3 odd days. So last day of second century is
‘Wednesday’. 300 years contain 15 odd days = 1 odd day.

. : Last day of 3rd century is ‘Monday’. 400 years contains 0 odd day.

: . Last day of  4th century is ‘Sunday’.

Since the order is continually kept in successive cycles, we see that the last day of a
century cannot be Tuesday, Thursday or Saturday

10. 2000 years have 2 odd days.

Number of odd days from 2001 –2009 = 11 odd days = 4 odd days. 1st January
2010 has 1 odd day. Total number of odd days = (2 + 4 + 1) =  7 = 0 odd day

: . 1st January, 2010 will be a Sunday.
