Answers:

1. 3

Total domestic investment by company C1

= 6000 + 3000 + 4000 + 3000 + 3500 + 2500 + 3500

= Rs. 25500 crore

Total foreign investment by company C1

= 3000 + 1600 + 2800 + 3000 + 2000 + 3500 + 1000

= Rs. 16900 crore

So, required difference = 25500 – 16900 = Rs. 8600 crore

2. 4

Total investment in Metals

= 4000 + 2800 + 3500 + 2000 + 3200 + 2200 + 2500 + 500

= Rs. 20700 crore

Total investment in Machinery

= 3000 + 3000 + 2500 + 3000 + 3600 + 6000 + 2000 + 2500

= Rs. 25600 crore

So, required ratio = 207 : 256

133. 1; Average domestic investment by company C4

= (6000 + 4000 + 2500 + 2000 + 4000 + 2200 + 2000)/7

= 22700/7 = Rs. 3243 crore

134. 5; Domestic investment by company C3

= 4000 + 5000 + 3200 + 3600 + 3000 + 2500 + 2400

= Rs. 23700 crore

Foreign investment by company C1= 3000 + 1600 + 2800 +

3000 + 2000 + 3500 + 1000 = Rs.  16900 crore

Required percentage = 23700/16900 * 100 = 140%

5. 2

Average domestic investment by company C2

= (2000 + 3000 + 3500 + 2500 + 2500 + 2000 + 500)/7

= Rs. 2286 crore

Average investment in transport

= (3500 + 2000 + 2500 + 3200 + 3000 + 2600 + 4000 + 2000)/4

= Rs. 5700 crore

So, required percentage = 2286/5700 * 100 = 40%

(6–10):

Girls = 3/7 * 5600 = 2400

Boys = 4/7 * 5600 = 3200

6. 1

Required ratio = 640 : 1280 = 1 : 2

7. 5

Required answer = 240

8. 3

Required answer = 600 + 480 = 1080

9. 2

Required percentage = 600/ (1280 + 960) * 100 = 600/2240 * 100 = 26.8%

10. 1

Required percentage more = {(1280 + 640) - 960} / 960 * 100 = 100% more
