Its a MUST BE TRUE Q

I am getting 1/t = 1/c + 1/h

hence t can be calculated by plugging values of c,h where c<h


is it I and III?both?

II cant be correct

for III to be correct we can take c=4 and h=7
where t becomes 28/11
so 4/2<28/11<7/2
whats the OA?

Aleehs - I posted the question so I can see how you solved it. I would highly recommend you post the solution before asking for OA.

Nitya- Thanks. OA is E.
