Correct Answer: (4) Both (2) and (3)
Solution:Between 8 and 9 O'clock t = 8,

Let t hour x minutes the angle between both hand is 80°

Case-I:

When hour hand ahead the minute hand

80° = [30(8 - x/5) + x/2]

80° = 240 - 6x + x/2

(11x)/2 = 160

x = (160 x 2)/11

= 320/11 = 29 1/11 minutes

Time = 8 hours 29 1/11 minutes

Case-II: When minute hand ahead the hour hand

80° = [30(x/5 - 8) - x/2]

80° = 6x - 240 - x/2

11x 2 = 320

640 11 2 11 ⇒x= = 58 minutes

Time = 8 hours 58 2 11 minutes
