- (a) Population increased by 5% or more every year.
- (b) Income increased by 10% or more every year.
- (c) Per capita income was always above ₹ 5,000. ✓ UPSC's answer
- (d) Per capita income was highest in 1994.
Why the answer is (c)
• Calculate per capita income for 1992: ₹1010 crores / 20 lakhs = ₹5,050.
• Calculate per capita income for 1993: ₹1111 crores / 21 lakhs ≈ ₹5,290.
• Calculate per capita income for 1994: ₹1225 crores / 22 lakhs ≈ ₹5,568.
• Calculate per capita income for 1995: ₹1345 crores / 23 lakhs ≈ ₹5,848.
• All calculated values (₹5,050, ₹5,290, ₹5,568, ₹5,848) are strictly greater than ₹5,000.
• Therefore, statement (c) is the only correct one.
Why the other options are wrong
- (a) Population increased by 5% or more every year.
- Population growth from 1992 to 1993 was only 5%, but from 1993 to 1994 it was approximately 4.76%, which is less than 5%.
- (b) Income increased by 10% or more every year.
- Income growth from 1994 to 1995 was approximately 9.79%, which is less than 10%.
- (d) Per capita income was highest in 1994.
- Per capita income was highest in 1995 (approx. ₹5,848), not in 1994 (approx. ₹5,568).
