B
80

C
120

D
200

Solution

The correct option is A $$40$$
Let the numbers be $$3x$$, $$4x$$ and $$5x$$.
Then, their L.C.M. $$= 60x$$.
So, $$60x = 2400$$ or $$x = 40$$.
$$\therefore $$ The numbers are $$\left( 3\times 40 \right) $$, $$\left( 4\times 40 \right) $$ and $$\left( 5\times 40 \right) $$.
Hence, required H.C.F. $$= 40$$.
