B) 11: 12
C) 9: 10
D) 7: 9
E) 4: 5
Correct Answer: C
Solution :
| Required ratio\[\text{=}\,\,\frac{\text{Population}\,\text{of}\,\text{state}\,\text{Q}}{\text{Population}\,\text{of}\,\text{state}\,\text{S}}\] |
| \[\text{=}\,\,\frac{\frac{225}{4}lakh}{\frac{125}{2}lakh}\,\,=\,\,\frac{225\times 2}{4\times 125}\] |
| \[=\frac{9}{2\times 5}=\frac{9}{10}=9:10\] |
