How many times in a day, the hands of a clock are straight?
A. 22 B. 24
C. 44 D. 48

• The hands of a clock point in opposite directions (in the same straight line) 11 times in every 12 hours.
  (Because between 5 and 7 they point in opposite directions at 6 o'clock only).
  
  So, in a day, the hands point in the opposite directions 22 times.

• 1) STRAIGHT LINE AND COINCIDE:
  In 12 hours,the short hand and long hand coincide 12 times (eg. 12.00,1.05,2.10,3.15,4.20,5.25,6.30,7.35,8.40,9.45,10.50,11.55) .Either 11.55 or 12.00 is taken because the difference between 11.55 and 12.00 is 5 minutes,,,,but short and long hand coincides for every 65 minutes difference.So,totally,,11 times in 12 hours and 22 times in a day.
  2) STRAIGHT LINE BUT OPPOSITE IN DIRECTION:
  In 12 hours,,the short hand and long hand are in a straight line but opposite in direction 11 times ,,(eg.12.30,1.35,2.40,3.45,4.50,5.55,6.00,7.05,8.10,9.15,10.20,11.25).Either 5.55 or 6.00 is taken ,,because the difference between consecutive numbers should be 65 minutes,,but the difference between 5.55 and 6.00 is 5 minutes.So ,it is excluded.For a day,,it is 22 times.
  3)Finally,the value is 22+22=44.The Answer is 44

• in a clock, from 1 to 24=every 5 hr .it happen i.e(1,6),(2,7)...... equal to=11
  so twice a day a clock =2*11=22
