Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 11: 25.
Calculations:
Let the total population be x.
Population of goa in 1998 = 12% of x
Population of goa in 1997 = 12% of x × 100/120
Population of arunachal pradesh in 1998 = 25% of x
Population of arunachal pradesh in 1997 = 25% of x × 100/110
Required ratio = 12% of x × 100/120 : 25% of x × 100/110
⇒ 11 : 25
