The ratio of the area of the sector CDEF to the area of the sector CBAF is nearly

Let angle made at centre by sector CDEF be $$\theta$$ and total investments be Rs. $$x$$

=> $$\theta=\frac{183+454+110}{x}\times360^\circ=747\times\frac{360^\circ}{x}$$

Similarly angle made by sector CBAF = $$\theta_1=\frac{107+458+227}{x}\times360^\circ=792\times\frac{360^\circ}{x}$$

$$\therefore$$ Ratio of the area of the sector CDEF to the area of the sector CBAF = $$\frac{\theta}{\theta_1}$$

= $$\frac{747}{792}\approx1$$

=> Ans - (A)
