A) Rs. 8820
B) Rs. 8125
C) Rs. 8610
D) Rs. 8804
Correct Answer: A
Solution :
: Area of larger rectangle \[=(32\times 25)\,c{{m}^{2}}=800c{{m}^{2}}\] Also, area of smaller rectangle \[=485\text{ }c{{m}^{2}}\] \[\therefore \] Area of shaded part \[=(800-485)\,c{{m}^{2}}=315c{{m}^{2}}\] Now, Cost of cementing of \[3c{{m}^{2}}=Rs.84\] \[\therefore \] Cost of cementing of \[1\,\,c{{m}^{2}}=(84\div 3)\] \[=Rs.28\] \[\therefore \] Cost of cementing of \[315\text{ }c{{m}^{2}}\] \[=Rs.\,(28\times 315)=Rs.\,8820\]
