Concept: 

Equation of hyperbola ,   

Length of latus rectum, L.R =  

 

Equation of hyperbola,  

Length of latus rectum, L.R =   

 

Calculation: 

Given equation are ,  25y2 - 24x2 = 600 

⇒  

On comparing with standard equation, a = 5 and b =  

We know that , length of latus rectum 

L.R =  =  

⇒ L.R = units .  

The correct option is 1.
