Data Sufficiency Practice Test 3

Using Statements I, II and III together:
Length of the rectangle = 6 meters
Breath of the rectangle = $\frac{2}{3}\times 6$ 3 = 4 meter
Area of the rectangle = 24 ${\mathrm{meter}}^2$
Cost of flooring the area of 100 ${\mathrm{cm}}^2$ is Rs 45.
Cost of flooring the of 24 area ${\mathit{m}}^2$ is 45 × 24 = Rs 1,080
Hence, the solution can be derived by using all Statement I, Statement II and Statement III together.
