A clock shows 5.20. After how much time both hands will coincide together?

a) 6 2/11 minutes
b) 5 5/11 minutes
c) 3 2/11 minutes
d) 4 2/11 minutes

• 60/55*(5)=5 5/11

• I think initial angle is 40deg. Now Let after x min. they'll coincide.
  Per min. Min hand moves 6 deg. and Hour hand - 0.5 deg.
  So,
  6x - 0.5x = 40 => x = 80/11minutes. So answer is none of these.
