. In a circlr track of lngth 100m..g m n k start togethr,g n m start in d same directn at speeds 10 n 8m/s..h runs in opp directn at 15m/s..whn wl al 3 meet fr frs time

1) 4secs
2) 50s
3) 200s
4) 100s

• they wl meet aftr 100 sec
  2 same direction(g & m)=let's assume s1=10m/s , s2= 8m/s
  1 opp.direction(h)=let's assume s3=15m/s
  length of the circular track L=100m
  Time taken to meet All 3 =LCM[L/s1-s2,L/s2+s3]
  =LCM[100/10-8,100/8+15]=100 sec
