Question

the circumference of four wheels of different cars are 60 cm, 75 cm, 9o cm and 108 cm they start moving simultaneously. what least distance should they cover so that each wheel makes a complete number of revolution
​

Answer 1

Answer:

the least distance which four vehicles cover...=The LCM of 60,75,90,and,108

2700cm is LCM

2700/100 m

27m

after 27 meters travel each wheel rotates complete rotations...

the rotations are as follows..

(2700/60)=45

(2700/75)=36

(2700/90)=30

(2700/108)=25

completes after travelling 27meters …

27metres is the least distance

after completion of..45,36,30,25 rotations..
