Rahul took part in a cycling game with many others in a circular closed circuit. After pedaling for several minutes, he found that 1/5th of the cyclists ahead of him and 5/6th of the cyclists behind him together formed the total no. of participants. How many were participating in the race?
Read Solution (Total 11)
-
- In the circle, the no. of cyclists ahead of Rahul = no. of cyclists behind him. And let the no. of participants in the race excluding Rahul be x.
so the total no. of participants in the race=x+1.
A/Q, x/5 + 5x/6 = x+1
On solving, we get x=30.
hence, the total no. of participants in the race= x+1= 30+1=31

- 30.
1/5 th are ahead,5/6th are behind and one himself(rahul).Now assume total no of participants to be x.
thus, x = (x/5)+(5x/6)+1
x/30=1
x=30. - 13 years agoHelpfull: Yes(7) No(15)
- let the number of participants be x.
then x/5 + 5x/6 + 1 = x (including rahul)
solvng we get 30.
u can get a doubt like, 1/5th of 30 is 6 and 5/6th of 30 is 25, when u sum all the three, 25+6+1 = 32.. but we got 30.
as it is a circle, the cyclist who is leading rahul, can also be behind him. if the track is a straight path, then this ans is not correct :-) - 13 years agoHelpfull: Yes(4) No(2)
- 1/5(x-1)+5/6(x-1)=x
x=31. - 10 years agoHelpfull: Yes(3) No(0)
- the solution to this problem can be given this way->
on a closed circuit say n participants are cycling.
except Rahul there are n-1 participants
therefore according to Rahul following linear equation can be framed->
1/5(n-1) + 5/6(n-1) = n - 11 years agoHelpfull: Yes(2) No(0)
- dera friends 1/5 th of 30 is 6
and 5/6 th of 30 is 25
so including rahul the total no. of cyclist as per u r answer would be 32
u r answer would not satisfy the equation - 13 years agoHelpfull: Yes(1) No(2)
- 30...let total no of particiants be x derefore d equation becomes x=x/5+5x/6+1.

- 1/5(x-1)+5/6(x-1)=x
=>31 - 10 years agoHelpfull: Yes(1) No(0)
- for rahul total no. of cyclist would be one less than total no. of participants
thus
the equation formed would be like this
x/5+5x/6=x-1
on solving this the sol is
30 - 13 years agoHelpfull: Yes(0) No(4)
- LCM of 5 & 6=30
After taking LCM, (1/5)+(5/6)=(6+25)/30=31/30
where numerator>denominator because we have included Rahul whereas 1/5 & 5/6 represents the other cyclists.
Hence answer is 31. - 7 years agoHelpfull: Yes(0) No(0)
- let the total number = x
since it is a closed circle = x-1
now,
(1/5+5/6)(x-1)=x
=>(31/30)(x-1)=x
=>(31/30)x-31/30=x
=>(1/30)x=31/30
therefore the number of people participating in the race is 31 - 6 years agoHelpfull: Yes(0) No(0)
