Answer»

The clock loses 10 minutes per hour

Here, the clock shows only 50 minutes for 60 minutes( in 1 hour)

The watch show the time 12 : 50, after 1 hour

Formula ,To find the angle between hour hand and minutes at H hours M minutes =30H – 11/2 M

The angle between the two hands of the clock after 1 hour

=30 x 12 – 11/2 x 50

= 360° - 11×25

=360º – 275º = 85º
