Two rigid bodies A and B rotate with angular momenta ${\mathrm{L}}_{\mathrm{A}} \mathrm{and} {\mathrm{L}}_{\mathrm{B}}$ respectively. The moments of inertia of A and B about the axies of rotation are ${\mathrm{I}}_{\mathrm{A}} \mathrm{and} {\mathrm{I}}_{\mathrm{B}}$ respectively. If ${\mathrm{I}}_{\mathrm{A}}={\mathrm{I}}_{\mathrm{B}}/4 \mathrm{and} {\mathrm{L}}_{\mathrm{A}}=5{\mathrm{L}}_{\mathrm{B}},$, Then the ratio of rotational kinetic energy ${\mathrm{K}}_{\mathrm{A}} \mathrm{of} \mathrm{A}$ to rotational kinetic energy ${\mathrm{K}}_{\mathrm{B}}$ of B is given by
