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
