A clock was set correct at 8 O' clock. It loses 10 minutes per hour. What will be the angle between the hour and minute hands of the clock after one hour ? |
35° 40° 42° 43° |
35° |
The clock loses 10 minutes per hour. Here, the clock shows only 50 minutes for 60 minutes ( in 1 hour ),
So, the formula is;
{ 30H - 11/2 M }
=> 30 x 8 - 11/2 x 50
=> 240 - 11 x 12
=> 240 - 275
=> (-) 35°
Thus, 35° is correct. |
