- Statement (A) is correct:
- Both Pakistan (6.3% to 5.3%) and China (10.3% to 6.8%) experienced a decline in GDP growth rates from 1980-90 to 2015-17. - Statement (B) is correct:
- China achieved double-digit GDP growth (10.3%) in 1980-90, making this statement accurate.
- Statement (C) is correct:
- India’s GDP increased from 5.7% to 7.3%, indicating moderate acceleration in 2015-17.
- Statement (D) is incorrect:
- Pakistan's growth rate (6.3%) was higher than India's (5.7%) in 1980-90, but in 2015-17, India's GDP (7.3%) surpassed Pakistan’s (5.3%), making this statement false. Conclusion: Since Pakistan was not ahead of India for the entire period from 1980 to 2017, the correct answer is option (D).



A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
