Answer:

10

Step-by-step explanation:

Angle traced by hour hand in 13/3 hrs = 360/12 x 13/3 ° = 130°.Angle traced by min. hand in 20 min. = 360/60 x 20 ° = 120°.

Required angle = (130 - 120)° = 10°.

We must recall that:

At 4 o'clock, minute hand is at 12 while the hour hand is at 4. Again the minute hand has to sweep through (30\times4) i.e., 120° for reaching the figure 4 to show 20 mins.

We can write 4 hrs. 20 mins. as \frac{13}{3} hrs.

Angle traced by hour hand in \frac{13}{3} hrs =30\times \frac{13}{3} =130°

∴ Angles between hands of clock =130° -120° =10°

Option D is correct.
