- If 10% of the land reserved for rice be distributed to wheat and barley in the ratio 2 : 1, then the angle corresponding to wheat in the new pie-chart will be:
-
View Hint View Answer Discuss in Forum
∴ New corresponding angle for wheat = Old corresponding angle for wheat + Increase in the corresponding angle of wheat
Correct Option: B
From above given chart ,
Corresponding angle for wheat is represented by 72°
10% of 72° = 7.2°
Ratio of wheat and barley = 2 : 1
∴ Increase in the corresponding angle of wheat= 2 x 7.2 = 4.8° 3
∴ New corresponding angle for wheat = Old corresponding angle for wheat + Increase in the corresponding angle of wheat
= 72° + 4.8° = 76.8°
- The combination of three crops which contribute to more than 50% of the total area under the food crops is:

From above given chart ,
∴ 100% = 360°
∴ 50% = 180°Correct Option: A
From above given chart ,
∴ 100% = 360°
∴ 50% = 180°
∴ wheat + rice + maize = 72° + 72° + 45° = 189° > 180°
Hence the total area of wheat , rice and maize food crops is more than 50% of the total area of given food crops .
- If the total area under bajra was 300 acres, then the total area (in hundred acres) under rice and barely together is :

As per given pie chart , we can see that
Angle for rice = 72°
Angle for barley = 36°
The total angle for rice and barley = 72° + 36° = 108°
Total area of bajra is represented by 18° = 300 acresCorrect Option: A
As per given pie chart , we can see that
Angle for rice = 72°
Angle for barley = 36°
The total angle for rice and barley = 72° + 36° = 108°
Total area of bajra is represented by 18° = 300 acres
∴ The total area in angle of rice and barely = 108°∴ 1 ° = 300 acres 18
∴ The total area in angle of rice and barely = 108°∴ The total area in acres of rice and barely = 300 x 108 = 1800 acres 18
- If the production of rice is 5 times that of jowar and the production of jowar is 2 times that of bajra, then the ratio between the yield per acre of rice and bajra is :
-

Let, the production of bajra be p tonnes.
∴ Required ratio = The yield per acre of rice : The yield per acre of bajraCorrect Option: A
Let, the production of bajra be p tonnes.
∴ Production of jowar = 2p tonnes
⇒ Production of rice = 10p tonnes
∴ Required ratio = The yield per acre of rice : The yield per acre of bajraThe yield per acre of rice = 10p 72 The yield per acre of bajra = p 18 ∴ Required ratio = 10p : p = 5 : 2 72 18
