Answers:
1)a   2)d   3)c   4)d   5)e   6)   7)   8)   9)   10)
Solutions:
1. A) Difference = 8.6 × 22/100 – 5.4 × 15/100 = 1.892 – 0.81 = 1.082 lakh
2. D) H2000 = 5.4 × 10/100 = 0.54 lakh,
H2010 = 8.6 × 8/100 = 0.688
Therefore Average = 0.54 + 0.688/2 = 1.228/2 lakh = 61400
3. C) Sum = 5.4 × 8/100 + 8.6 × 18/100 = 0.432 +1.548 = 1.98 lakh
4. D) Total number of vacancies in 2010 = 48000 × 100/6 = 800000
Therefore vacancies in NCR = 20% of 800000 = 160000
5. E) H2000 = 5.4 × 10/100 = 0.54 lakh
H2010 = 8.6 × 8/100 = 0.688 lakh
Therefore % rise = (0.688 – 0.54)/0.54 x 100 ≈ 27.4%
