Let us assume 5 + 2v3 is rational, then it must be in the form of p/q where p and 
q are co-prime integers and q ? 0   
i.e 5 + 2v3 = p/q 
 So v3 = 
?? -5?? 2?? ……………………(i) 
Since p, q, 5 and 2 are integers and q ? 0, HS of equation (i) is rational. But 
LHS of (i) is v3  which is irrational. This is not possible. 
This contradiction has arisen due to our wrong assumption that 5 + 2v3 is 
rational. So, 5 + 2v3 is irrational.

Then  2a + 2ß = -p 
          2(a + ß) = -p 
          2 x 5/2 =-p 
So p = -5 
And  2a x 2ß = q 
            4 aß = q  
   So q = 4 x-3/2

Since p, q, 5 and 2 are integers and q ? 0, HS of equation (i) is rational. But 
LHS of (i) is v3  which is irrational. This is not possible. 
This contradiction has arisen due to our wrong assumption that 5 + 2v3 is 
rational. So, 5 + 2v3 is irrational.

Let the actual speed of the train be x km/hr and let the actual time taken be y hours. 
Distance covered is xy km 
If the speed is increased by 6 km/hr, then time of journey is reduced by 4 hours i.e., 
when speed is (x+6)km/hr, time of journey is (y-4) hours. 
? Distance covered =(x+6)(y-4) 
?xy=(x+6)(y-4)

Similarly xy=(x-6)(y+6)   
?6x-6y-36=0 
?x-y-6=0 ………………………………………(ii) 
Solving (i) and (ii) we get x=30 and y=24 
Putting the values of x and y in equation (i), we obtain 
Distance =(30×24)km =720km. 
Hence, the length of the journey is 720km.
