While i cross checked, and i find the solution
for A and B : 20 min ---- 200m
10 min ----- 100m
5 min ------- 50m

for B and C : 10 min ---- 250 m
2min ------ 50 m (as to make both b as same , make it to 50 m by dividing it by 5)


for A and C : as both b are in 50 m, so A and C will be 5+ 2 = 7m apart
as A beat C in 100 m race (50 *2) so 7 *2= 14 min will be the exact answer!!

A : B = 200 : 180.

B : C = 250 : 240.

A/C = (A/B * B/C) = (200/180 * 250/240) = 125: 108 { IN THE B metres i have confusion as they should actually be same)

When A covers 125 m, C covers 108 m.

When A covers 100 m, C covers (108/125 * 100) m = 86.4 m.

Therefore, A beats C by (100 - 86.4) m = 13.6 m.



please if any more adequate, kindly contradict on the same!

ans 14 meters A beats B by 25 min in 250 m race hence from data A beats C by 35min in 250 m race hence A beats C by 14 min in 100m race

Let the race be for 100min
A takes 100min to complete 200 Mts race
B takes 80 min to complete same 200 Mts race.
Now for 100mts A take 50 min and B take 40 min.......
A:B=50:40
In a race of 250 Mts
B takes 100min ,C takes 90 min
So B takes 40 min for 100 Mts race whereas C takes 36 Min....
So B:C=40:36
Now
A:B::B:C=50:40::40:36 for entire 100mts race.
A:C=25:18
So A beat C by 7 min exactly......
