a hare and a tortoise a race along a circle of 100 yards dia.the tortoise goes in 1 direction n the hare in te other.the hare starts after tortoise has covered 1/5 its distance .the hare n tortoise meet when te hare has covrd 1/4 of te distanc.by wat factor should hare increase its speed so as to tie te race?
options
8
37
45
6.6
need a easy way to solve frnds:)

• see the option which one is decimal that is ans for this type of ques in TCS

• formula:(h-1)(h-1-h/t)
  h=4;t=5;
  then ans 6.6

• the answer is 6.6
  Just forget 100 yards given in problem...
  Multiply 5 by 4(numbers given in denominator of fraction) we get 20 yards...
  Now Hare starts when tortoise had covered (1/5) of 40 yards i.e 4 yard...
  tortoise meet the hare when hare has covered (1/4) of 40 yards i.e 5 yards..
  Now suppose speed of Tortoise is "T" and that of Hare is "H"..therefore
  (H/T)= (5/11)..[in the same time hare travels distance of 5 yards while tortoise travels 11 yards]..
  now to tie the race hare must have increase it's speed...
  to tie the race the ratio of H & T must be (15/5)i.e 3...
  suppose by factor 'x' hare has to increase it's speed..
  therefore,
  (5/11)*x = 3..
  x = 3*(11/5)
  x= 6.6

• ans is 6.6 always see for . result

• distance of hare distance of tortoise
  0 (rest) 20yards(1/5)
  25yds(1/4) 55yds(100-45)
  now hare crossd now tortoise
  25 yds 75yds
  hare want 2 go 75 yds and tortoise just 25yds so hare want 2 speed up
  75t/25h=25/55
  h=6.6t ans 6.6

• vandana says,
  6.6 will be answer here.. :)

• in this problem at first find the ratio of the distance covered by the turtle with compare to the hare
  means-(100(total)-25(cover by hare)-20(all ready covered by turtle))/25
  =(55/25)=2.2
  and than fine distance left to cover by the hare.
  then (100-25(all ready coverd))/25=75/25=3
  and multiply these two 2.2*3=6.6
