Question

2. Three boys steps off together from the same spot.
Their steps measures 65 cm, 70 cm and 75 cm
respectively. What is the minimum distance each
should cover so that all can cover the distance in
complete steps ?​

Answer 1

For finding minimum distance, we have to find L.C.M of 63, 70, 77.

L.C.M. of 63, 70 and 77 = 7 x 9 x 10 x 11 = 6930 cm.

Therefore, the minimum distance is 6930 cm.

Answer 2

L.C.M. of 63, 70 and 77 = 7 x 9 x 10 x 11 = 6930 cm. Therefore, the minimum distance is 6930 cm.
