The Correct Option is A
Solution and Explanation
From the figure, the number of floors on each plot is: A = 3, B = 4, C = 1, D = 2, E = 4, F = 1.
Total floors = 3 + 4 + 1 + 2 + 4 + 1 = 15.
Commercial plots A, D, E: 3 + 2 + 4 = 9 floors, so 9/15 x 100 = 60%.
Residential plots B, C, F: 4 + 1 + 1 = 6 floors, so 6/15 x 100 = 40%.
Answer: (1) 60% and 40%
Total floors = 3 + 4 + 1 + 2 + 4 + 1 = 15.
Commercial plots A, D, E: 3 + 2 + 4 = 9 floors, so 9/15 x 100 = 60%.
Residential plots B, C, F: 4 + 1 + 1 = 6 floors, so 6/15 x 100 = 40%.
Answer: (1) 60% and 40%

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
