Question

Three persons A, B and C run on a round track. A takes 100 seconds, B takes 110 seconds and C takes 120 seconds to run a round. If they start together when do they meet again?

Answer 1

Answer: They will meet again in 6600 seconds

Step-by-step explanation:

A takes 100 seconds to run a round

B takes 110 seconds to run a round

C takes 120 seconds  to run a round

To find when do they meet again we have to find LCM

100 = 2 x 2 x 5 x 5

110 = 11 x 5 x 2

120 = 2 x 2 x 2 x 3 x 5

LCM = 2 x 2 x 2 x 3 x 5 x 5 x 11 = 6600

LCM = 6600

Step-by-step explanation:

A take 100 second to run a round

B take 110 second to run a round

C take 120 second to run a round

To find when do they meet again we have find LCM

100=2×2×5×5

110=11×5×2

120=2×2×2×3×5

LCM= 2×2×2×3×5×5×11=6600

LCM= 6600
