Q. For a car there are 5 tyres including one spare tyre(4+1). All tyres are equally used. If the total distance travelled by the car is 40000km then what is the average distance travelled by the each tyre?

Option
a) 10000
b) 40000
c) 32000
d) 8000

• total distance travelled by the car=40000km
  so total distance travelled by 4 wheels=4*40000=160000
  as all tyres(4+1) are equally used
  so average distance travelled by the each tyre=160000/5=32000
  option(c)

• there are total 5 tyres {including stepne} so total distance =40000
  and distace covered by each tyre is =40000/5 means 8000.
  but this not the answer,because there are only 4 tyres on working,meanwhile stepne is on rest.so 40000-8000=32000 is your answer

• pls can u explain me the solution clearly.....
  I have a doubt that with the help of four tyres the car has travelled 40000km...then how can we consider the distance travelled by each tyre??

• yes,, Rakesh's answer is correct
• 10 years agoHelpfull: Yes(6) No(2)
• total distance travelled by the car=40,000km
  all 5 tyres are equally used
  so average distance travelled by the each tyre =40000/5=8000
  option(d)

• total distance hd bn said here that is 40000......do we need to multiply it again with 4?...its simple 40000/5=8000...

• is the answer provided by @rakesh right?

• rakesh is coorect bcoz spare tyre means front tyre which moves by back tyres.
  As 4 tyres travels 4*40000
  avg=160000/(4+1)
  1 is added to find avg. of all tyres.

• the correct ans is c
  as total distance= 40000x4
  =160000
  now
  160000/5
  32000

• but all the tyres are equally used
  so 40000/5=8000
• 8 years agoHelpfull: Yes(2) No(0)
• = [(40000*4) / 5] =32000
  
  40000 -> total distance
  4 -> running tyres
  5 -> (4+1) including spare tyres replacing at regular interval

• total distance with 4 tyres=40000*4=160000
  so ans=160000/5=32000
• 9 years agoHelpfull: Yes(1) No(0)
• 40,000*4=1,60,000 and then 1,60,000/5 = 32,000 so ans is c

• total distance travelled by the car=40000km
  so total distance travelled by 4 wheels=4*40000=160000
  as all tyres(4+1) are equally used
  so average distance travelled by the each tyre=160000/5=32000

• 4 years agoHelpfull: Yes(0) No(0)
• since car has only 4 tyres.so each tyre:40,000km
  total=40,000*4=160000
  5 tyres will run 160000/5=32000km each
