Study the given graph and table and answer the following question.
Data of different states regarding population of states in the year 1998
Total population of the given states = 32760000
If in the year 1998, there was an increase of 20% in the population of Goa and 10% in the population of Arunachal Pradesh compared to the previous year, then what was the ratio of populations of Goa and Arunachal Pradesh in 1997?
Answer & explanation
Correct answer: option 2
20% = \(\frac{1}{5}\) , 10% = \(\frac{1}{10}\) , 12 % = \(\frac{3}{25}\)
& 25% = \(\frac{1}{4}\)
Population of Goa in 1997 = \(\frac{5}{6}\) × \(\frac{3}{25}\) × 3276000
= 327600
Production of Arunachal Pradesh in 1997 = \(\frac{10}{11}\) × \(\frac{1}{4}\) × 3276000
= \(\frac{10}{11}\) × 819000
Required ratio = 327600 : \(\frac{10}{11}\) × 819000
= 11 : 25
