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 ratio of the production of wheat by the Conventional Method in Pakistan to that by the Scientific Method in Japan is
A9:40
B99:260
C51:260 ✓ Correct
D49:40
Correct answer: (C) 51:260
Explanation
The ratio is 51 to 260, so the answer is 51 to 260.
Pakistan's conventional production is 50 times 9 percent times 34 percent, which is 1.53 lakh tonnes.
Japan's scientific production is 50 times 20 percent times 78 percent, which is 7.8 lakh tonnes.
So the ratio is 1.53 to 7.8.
Multiplying both by 100 gives 153 to 780.
Dividing both by 3 gives 51 to 260.
So the ratio is 51 to 260.
