In a circular track of length 100m..A,B,C start togethr,A,Bstart in d same directn at speeds 10 n 8m/s..C runs in opp directn at 15m/s..when will all 3 meet for first time?
Read Solution (Total 3)
-
- time for a to complete one round =100/10
by b=100/8
by c=100/15
so to get time after they meets is=lcm of all numerator/hcf of all denominator
hence time=lcm(100,100,100)/hcf(10,8,15)
so, time =100/1=100 second - 11 years agoHelpfull: Yes(19) No(0)

- time 4 one round by a = 100/10=10 sec.
by b= 100/8=25/2
c=100/15=20/3
now a &c wil meet aftr= 100/reltv speed= 100/15-10=20 sec.
b&c meet= 100/7
all 3 wil meet = l.c.m.(20,100/7)= 100 sec. - 11 years agoHelpfull: Yes(3) No(0)
