 A) 110 B) 120 C) 130 D) 140

Explanation:

Angle traced by hour hand in 12 hrs. = 360º.

Angle traced by it in $113$hrs =$36012×1130$$1100$

Angle traced by minute hand in 60 min. = $3600$

Angle traced by it in 40 min = $36060×400$$2400$

$\inline \fn_jvn \therefore$Required angle (240 - 110)º = $1300$
