SOLUTIONS

1. (1) Production In Indonesia  = 50 * 10/100 = 5 lakh tones

Difference= 5 * (73 – 27) /100 = 2.3 lakh tones

2. (2) Production of wheat by scientific method in

India= 50 * (18/100) * (32/100) = 2.88 lakh tones

Japan = 50 * (20/100) * (78/100) = 7.8 lakh tones

China= 50 * (22/100) * (70/100) = 7.7 lakh tones

Bangladesh= 50 * (8/100) * (20/100) = 0.8 lakh tones

Pakistan= 50 * (9/100) * (66/100) = 2.97 lakh tones

Indonesia= 50 * (10/100) * (73/100) = 3,65  lakh tones

Sri Lanka= 50 * (13/100) * (60/100) = 3.9 lakh tones

So Avrg = (2.88 + 7.8 + 7.7 + 0.8 + 2.97 + 3.65 + 3.9)/7 = 4.24 lakh tones

3. (3) Production by conventional method in Pakistan = 50 * (9/100) * (34/100) = 1.53 lakh tones

Production by scientific method in Japan= 7.8 lakh tones

Required ratio= 1.53 : 7.8 = 51 : 260

4. (3) Production of wheat in Sri Lanka by Conventional method= 50 * (13/100) * (40/100) = 2.6 lakh tones

Production in India by scientific method= 50 * (18/100) * (32/100) = 2.88 lakh tones

According to question, 2.88 * x = 2.6

x = 2.6/2.88 = 0.9 times

5. (5) Production of wheat in India by Scientific method= 50 * (18/100) * (32/100) = 2.88 lakh tones

Production in Pakistan by Conventional method=50 * (9/100) * (34/100) = 1.53 lakh tones

According to question = 2.88/1.53 = 1.88 times

6. (b) Ratio of cost

7. (a) Required percentage

8. (c) Required percentage

9. (d) Required Difference

10. (b) We can see from the graph that for industrial sector, the usage is increased from 25 to 49 which is 96%. Hence, this is the maximum increase. For no other sector the usage became almost double.
