Option 1 : (30 + 10/11) minutes past 2 and (34 + 6/11) minutes past 4

According to question,

x + y = 180

x – y = 40

Solving both the equations, x = 110 and y = 70

Clock A

Angle between the hands = 11 × m/2 – 30 H

m denotes the minute hand and H denotes the hour hand

Angle = 110 degrees               H = 2

110 = 11 × m/2 – 30 × 2

m = 340/11 = (30 + 10/11)

Time on Clock A is (30 + 10/11) minutes past 2.

Clock B

Angle between the hands = 11 × m/2 – 30 H

m denotes the minute hand and H denotes the hour hand

Angle = 70 degrees                 H = 4

70 = 11 × m/2 – 30 × 4

m = 380/11 = (34 + 6/11)

Hence, Time on Clock B is (34 + 6/11) minutes past 4.
