RACES:
There are two types of Races are there they are Linear Races and Circular Races
Type 1: LINEAR RACES:
1.In a Race of 100 metre ,A beats B by 20 metre and beats C by 30m.Then in a race of 100 m by how many metre will B beats C?
If A runs 100 metre then B will run 80 metre ,If A ru 100 metre then C will run 70 metre.
| A | B | C |
| 100 | 80 | 70 |
B beats C by
(10/80)*100=12.5metres
2.In a Race of 100 m A beats B by 20 m and in other Race B beats C by 30 m .then fow many metres A beats C?
| A B A |
| B C C |
| 100 100 100 |
| 80 70 56 |
A beats C by 44m(100-56=44m)
# 2.TYPE 2:
CIRCULAR RACE:
1.A,B and C participated in a Circular Race and A completes the race in 20 sec B in 15 sec and C in 10 secs if all the three starts at the same time and the same point then find when all will meet at the first time?
A completes the circular field at 20,40,60..sec
B completes the circular field at 15,30,45,60…sec
C completes the circular field at 10,20,30,40,50,60.sec.
So they will meet in 60th sec
Hint :
For first meet at starting point just take LCM if they move in same direction as well as in opposite direction
LCM(20,15,10=60sec)
2.A and B moves around a circular field if A completes the circular field in 25 sec and B completes the circular field in 20 sec then at what time they will meet the first time?
| Opposite Direction: | Same Direction |
| Speed of A=A
Speed of B=B Relative Speed=A+B |
Speed of A=A
Speed of B=B Relative Speed=A-B |
| Speed | Time | Distance |
| Speed of A=D/25 | 25sec | D |
| Speed of B=D/20 | 20sec | D |
=D/((D/25)+(D/20))=500D/45D=100/9sec
