The angle between two hands at 3.45 is

a) 110 degree
b) 115 degree
c) 112 1/2 degree
d) 117 degree

• theta degree=11/2m-30h //formuae
  =11/2(45)-30(3)
  =247.5-90
  =157.5 or 157 1/2 degree

• 3.45
  3*60=180
  180+45=225
  225/2=112.05

• In 12 hrs angle made by hour hand is 360 degree.
  In 60 minutes angle traced by minutes hand is 360 degree.
  Now for hour hand-In 1 hours angle will be=360/12=30 degree..............for 3:45 minutes means (3+3/4)=15/4 hrs..........Total angle moved in 15/4 hours will be=15/4*30=225/2 degree
  
  Now for same as minutes hand,In 1 minutes=360/60=6 degree.................No in 45 minutes=6*45=270 degree
  Difference between two hands in angle is=270-225/2=157.5 Ans
