3 hours 35 min$=3\frac{35}{60}=\frac{43}{12}$ hours.
Angle made by hour hand in 12 hours= 360°
∴Angle made by hour hand in $\frac{43}{12}$ hours
$=\frac{360°}{12}\times \frac{43}{12}=107.5°$
Angle made by minute hand in 60 min = 360°
∴ Angle made by minute hand in 35 min
$=\frac{360°}{60}\times 35=210°$
Thus, angle between hour and minute hand
$=210°-107.5°=102.5°$
