**Correct Answer :**

D. 24 cm

Volume of the liquid in the cylindrical vessel = Volume of the conical vessel

= ((1/3)* (22/7)* 12 * 12 * 50) )cm^{3 }= (22 *4 *12 * 50)/7 cm^{3}.

Let the height of the liquid in the vessel be h.

#### Then (22/7)*10*10*h =(22*4*12*50)/7 or h = (4*12*50)/100 = 24 cm
