Step-by-step explanation:
we will find the lcm
Now, HCF of 12,15,18
12=3*2*2
15=3*5
18=3*3*2
lcm of 12m,15m,18m =180m
so they will meet after 180m

Answer:
the distance crossed by Suraj =15
the distance crossed by Rohit =12m
the distance crossed by montu=18m
lcm= 15,12,18=180m
the distance between starting point and finishing point =180m
no.of hurdles crossed by suraj=180÷15=12
no. of hurdles crossed byrohit=180÷12=15
no. of hurdles crossed by montu =180÷18=10
