Correct Answer: 11 : 25


Solution : The population of Goa in the year 1998 = $32760000 \times \frac{12}{100}$
= 3931200
Population of Goa in the year 1997 = $3931200 \times \frac{100}{120}$
= 3276000
Population of Arunachal Pradesh in the year 1998 = $32760000 \times \frac{25}{100}$
= 8190000
Population of Arunachal Pradesh in the year 1997 = $8190000 \times \frac{100}{110}$
= $\frac{81900000}{11}$
Ratio = $3276000 : \frac{81900000}{11} = 11 : 25$
Hence, the correct answer is 11 : 25.
