A Clock was set correct at 10 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 ?

Solution

Correct Option: 3

After 1 real hour, the clock shows 10:50 (loses 10 min). At 10:50 the minute hand is at 10 (300^\circ) and hour hand is at 10×30+50×0.5=300+25=32510\times 30+50\times 0.5=300+25=325^\circ. Angle = 325300=25|325-300|=25^\circ.
