Answer 1

The correct option is C 17.32%

Explanation:

1995	1996	1997	1998	1999	2000
Population (in lakhs)	13	14.5	17	18.4	19.1	20.7
Total income (in crores)	874	913	1123	1329	1411	1426
Per-capita income (in Rs.)	6723.08	6296.55	6605.88	7222.83	7387.43	6888.89

Maximum difference = 7387.43-6296.55 = 1090.88

% difference $=\frac{1090.88}{6296.55}\times 100=17.32\%$
