25. Two persons take steps of 77 cm and 88 cm, respectively. If they start in step, then what is the minimum distance (in cm) they should cover so that both of them can cover the distance in complete steps? [SSC MTS 01/09/2023 (1st Shift)]

Correct Answer: (c) 616
Solution:

According to the question, LCM of 77 and 88 = 616
So the required answer will be 616 cm

28. Two trains started from a station, at the same time in the same direction, at speeds of 90 km/h and 80 km/h. What will be the distance between the two trains after 5 hours? [SSC MTS 04/09/2023 (2nd Shift)]

Correct Answer: (b) 50 km
Solution:

Relative speed of the train = (90 - 80) km/h = 10 km/h
Required distance = 10 × 5 = 50 cm
