Given : Every time the long arm completes a revolution,

the short arm in the stopwatch moves to the next division.

The watch was stopped, when the long arm was 4140° away from its start position.

To Find : the short arm would be how much away from its start position.

 60°

66°

69°

72°

Solution:

There are 60 Divisions in stop watch  

Every time the long arm completes a revolution,

the short arm in the stopwatch moves to the next division.

=> for every 360° of   long arm    =  (1/60) * 360°   of Short Arm

=>  for every 1° of   long arm    =  (1/60)°  of Short Arm

=>  for every 4140° of   long arm    =   4140 * (1/60)°  of Short Arm

=>  for every 4140° of   long arm    =  69°  of Short Arm

Hence  the short arm would be 69°  away from its start position.
