Direction: The bar graph given below shows the per acre yield (in kg) of different countries. Study the graph carefully and answer the questions.
-
Writing the yields of all countries in ascending order, the difference between the sum of yields of first three countries to that of last three countries is
-
- 200 kg.
- 212 kg.
- 172 kg.
- 162 kg.
Correct Option: C
From the given bar diagram , we see
Ascending order of yield per acre : 80 < 120 < 120 < 132 < 160 < 200
Sum of yields of first three countries = 132 + 160 + 200 = 492
Sum of yields of last three countries = 80 + 120 + 120 = 320
Required difference = Sum of yields of first three countries - Sum of yields of last three countries
∴ Required difference = (492 – 320) kg. = 172 kg.
