Answer 1

Let the speeds of Ajay, Vijay and Anujay be a, b and c. 

Let the time taken by ajay to cover 600m be t. 
Therefore, vijay covers (600-60)m = 540m in time t. 
Speed of 
ajay = 600/t 
vijay = 540/t 
a / b=10 / 9.................................Eq 1 

Similarly, 
Let the time taken by vijay to cover 500m be t. 
Therefore, anujay covers (500-25)m = 475m in time t. 
Speed of 
vijay = 600/t 
anujay = 540/t 
b / c=20 / 19................................Eq 2 

Multiply eq 1 by eq 2 - 
a / c = 200 / 171 

Therefore, the time in which Ajay covers 200m, Anujay will cover 171m 
Or, 
the time in which Ajay covers 400m, Anujay will cover 342m 

Thus, ajay will beat anujay by 400-342m = 58m 

I Hope that helped
