A) \[\text{Rs}.\text{223}.\text{5}0\]
B) \[\text{Rs}\text{. 298}.\text{37}\]
C) \[\text{Rs}\text{.353}.\text{17}\]
D) \[\text{Rs}.\text{192}.\text{53}\]
Correct Answer: B
Solution :
| [b] Radius of window \[=\text{35 cm}\] |
| Area of glass for 1 window \[=\pi {{r}^{2}}\] |
| \[=\frac{22}{7}\times 35\times 35=3850\,c{{m}^{2}}\] |
| \[\therefore \] Area of glass for 5 windows |
| \[=(5\times 3850)c{{m}^{2}}=19250c{{m}^{2}}\] |
| Cost of glass per \[{{m}^{2}}\] or \[10000\,c{{m}^{2}}=Rs.155\] |
| \[\therefore \] Cost of glass for |
| \[19250\,c{{m}^{2}}=\left( \frac{155}{10000}\times 19250 \right)=Rs.298.37\] |
