Answers:

  1. 2; Foreign investment in fuel in 2013 = 17500 – (1500 + 1000 + 2800 + 1500 + 5000 + 1200 + 2000) = 17500 – 15000 = Rs. 2500 cr
    Total domestic investment in 2013 = 5000 + 3000 + 4000 + 2000 + 2500 + 1500 + 3500 = Rs. 21500 crore
    Domestic investment in Industries in 2013 = 24000 – (2000 + 1000 + 1500 + 4000 + 3000 + 6000 + 1500) = 24000 – 19000 = Rs. 5000 cr
    Total foreign investment in 2013 = 2000 + 1600 + 2800 + 3000 + 2000 + 2500 + 1000 = Rs. 14900 crore
    Required difference = 21500 – 14900 = Rs. 6600 crore
  2. 5; Total domestic investment in Metals in 2014 = 13000 – (1000 + 3000 + 2500 + 1500 + 1000 + 500) = 13000 – 9500 = Rs. 3500 cr
    = 4000 + 2800 + 3500 + 2000 + 3200 + 2200 + 1500 + 500 = Rs. 19700 crore
    Foreign investment in Machinery in 2015 = 23800 – (3000 + 2800 + 2200 + 1600 + 5000 + 3200) = 23800 – 17800 = Rs. 6000 cr
    Total investment in Machinery = 2000 + 3000 + 2500 + 3000 + 3600 + 6000 + 1000 + 1500 = Rs. 22600 crore
    Required ratio = 19700 : 22600 = 197 : 226
  3. 3; Domestic investment in cement in 2016 = 23700 – (3000 + 1600 + 3000 + 2500 + 5000 + 2800 + 1800) = 23700 – 19700 = Rs. 4000 cr
    Average domestic investment in 2016 = 6000+4000+1500+1000+4000+1200+2000/7 = 19700/7 = Rs. 2814.28 crore
  4. 3; Required percentage = 22700/14900*100 = 152.3%
  5.  5; Average domestic investment in 2013 = 21500/7 crore Rs.
    Foreign investment in Transport in 2014 = 19000 – (1500 + 2500 + 2000 + 3000 + 2800 + 4000) = 19000 – 15800 = Rs. 3200 cr
    Average investment in transport = 2500+2000+1500+3200+3000+1600+ 4000+1000/4 = Rs. 4700 crore
    Required percentage = (21500*100)/ (7*4700) = 65.34%
  6. 3; Required number = 80 + 78 + 84 = 242
    Required percentage = 242/500*100 = 48.4%
  7. 4; Required ratio = 90/54 = 5 : 3
  8. 2; Required percentage = 78/500*100 = 15.6%
  9. 5; Required Difference = 50 – 30 = 20
  10. 5; Passed students in paper P2 and P3 but failed in P1 = 75
