1.	The circumference of four wheels are 50 cm, 60 cm, 75 cm and 100 cm respectively. They start moving simultaneously. What least distance should they cover so that each wheel makes complete number of revolutions? *
Answer» Answer: We'll find LCM LCM of 50, 60, 75 and 100 = 2 × 2 × 5 × 5 × 3 = 300. Hence, At 300 cm [ 3m ] each will MAKE a COMPLETE NUMBER of revolution.

Answer:

We'll find LCM

LCM of 50, 60, 75 and 100 = 2 × 2 × 5 × 5 × 3 = 300.

Hence,

At 300 cm [ 3m ] each will MAKE a COMPLETE NUMBER of revolution.
