Table shows the percentage of wheat production in seven countries and the Scientific vs Conventional method shares. Total production = 50 lakh tonnes.
| Country | Production (%) | Scientific (%) | Conventional (%) |
|---|---|---|---|
| India | 18 | 32 | 68 |
| China | 22 | 70 | 30 |
| Japan | 20 | 78 | 22 |
| Sri Lanka | 13 | 60 | 40 |
| Indonesia | 10 | 73 | 27 |
| Pakistan | 9 | 66 | 34 |
| Bangladesh | 8 | 20 | 80 |
The approximate average production of wheat, in lakh tonnes, by the Scientific Method for all seven countries is
A3.06
B3.16
C4.12
D4.24 ✓ Correct
Correct answer: (D) 4.24
Explanation
The average is about 4.24 lakh tonnes, so the answer is 4.24.
For each country, the scientific production is its distribution share times its scientific share of 50 lakh tonnes.
Adding these for all seven countries gives a total scientific production of about 29.7 lakh tonnes.
The average is this total divided by the seven countries.
So it is 29.7 divided by 7.
That is about 4.24.
So the average is about 4.24 lakh tonnes.
