JEE Advanced 2020 Concept Recapitulation Test 4 Paper 2

Moment of inertia of an equilateral triangular plate of side length a, about an axis passing through one of its vertices perpendicular to its plane is equal to I0. If the following symmetric structure is made from the same material, then its moment of inertia about the axis OO′ is found to be equal to NI0. Find N
