The Wheels Revolve Round A Common Horizontal Axis. They Make 15, 20 And 48 Revolutions In A Minute Respectively. Starting With A Certain Point On The Circumference Down Wards. After What Interval Of Time Will They Come Together In The Same Position?

Answer»

Time for one revolution = 60/15 = 4

60/ 20 = 3

60/48 = 5/4

LCM of 4, 3, 5/4

LCM of Numerators/HCF of DENOMINATORS

60/1 = 60.

Time for one revolution = 60/15 = 4

60/ 20 = 3

60/48 = 5/4

LCM of 4, 3, 5/4

LCM of Numerators/HCF of Denominators = 

60/1 = 60.
