Answer (Detailed Solution Below)
Bar Graph and Pie Chart Question 2 Detailed Solution
Concept:
If a is x% of y
Then, a = (x/100) × y
If n numbers are given
Then, Average = Sum of n numbers/n
Calculation:
Number of B+ blood group donors in camp A = 20000 × (28/100) × {1 – (65/100)}
⇒ 20000 × (28/100) × (35/100) = 1,960
Number of B+ blood group donors in camp B = 20000 × (18/100) × {1 – (55/100)}
⇒ 20000 × (18/100) × (45/100) = 1,620
Number of B+ blood group donors in camp C = 20000 × (12/100) × {1 – (45/100)}
⇒ 20000 × (12/100) × (55/100) = 1,320
Number of B+ blood group donors in camp D = 20000 × (26/100) × {1 – (30/100)}
⇒ 20000 × (26/100) × (70/100) = 3,640
Number of B+ blood group donors in camp E = 20000 × (16/100) × {1 – (70/100)}
⇒ 20000 × (16/100) × (30/100) = 960
Average number of B+ blood group donors in all given camps = (1960 + 1620 + 1320 + 3640 + 960)/5
⇒ 9500/5 =1,900
∴ Average number of B+ blood group donors in all of given camps is 1,900.

Number of other blood group donors in camp E = 20000 × (16/100) × (70/100) = 2,240
Total number of other blood group donors in all camps = 3640 + 1980 + 1080 + 1560 + 2240 = 10,500
Number of B+ blood group donors in camp A = 20000 × (28/100) × {1 – (65/100)}
⇒ 20000 × (28/100) × (35/100) = 1,960
Number of B+ blood group donors in camp B = 20000 × (18/100) × {1 – (55/100)}
⇒ 20000 × (18/100) × (45/100) = 1,620
Number of B+ blood group donors in camp C = 20000 × (12/100) × {1 – (45/100)}
⇒ 20000 × (12/100) × (55/100) = 1,320
Number of B+ blood group donors in camp D = 20000 × (26/100) × {1 – (30/100)}
⇒ 20000 × (26/100) × (70/100) = 3,640
Number of B+ blood group donors in camp E = 20000 × (16/100) × {1 – (70/100)}
⇒ 20000 × (16/100) × (30/100) = 960
Total number of B+ blood group donors in all camps = 1960 + 1620 + 1320 + 3640 + 960
⇒ 9,500
Difference in total number of other blood group donors in all camps and total number of B+ blood group donors in all camps = 10500 – 9500 = 1,000
∴ Difference in total number of other blood group donors in all camps and total number of B+ blood group donors in all camps is 1,000.

Number of boys study in IIT Delhi = 20000 × (18/100) × (55/100) = 1,980
Number of girls study in IIT Madras = 20000 × (12/100) × {1 – (45/100)}
⇒ 20000 × (12/100) × (55/100) = 1,320
Let, Number of boys study in IIT Delhi is x% of the number of girls study in IIT Madras
x% = (1980/1320) × 100
⇒ 150%
∴ Number of boys study in IIT Delhi is 150% of number of girls study in IIT Madras.
Bar Graph and Pie Chart Question 9:
Comprehension:
Direction: A data has been collected for 20000 families of 5 towns of a district. The pie-chart shows the percentage of total families under survey who are getting the benefit of government subsidy in 5 towns. The bar graph shows the quantity in kg of Rice and Wheat which is been given to each family.
Study the graphs carefully and answer the following questions.
If the government buys rice and wheat at Rs. 25 per kg and Rs. 18 per kg from the farmers then find the amount of loss to the government from town D. (Subsidised rate of rice is Rs. 3 per kg and that of wheat is Rs. 2 per kg)
Answer (Detailed Solution Below)
Bar Graph and Pie Chart Question 9 Detailed Solution
Calculation:
Total number of families under survey = 20000;
∴ Number of families from town D = 20000 × 0.20 = 4000
According to the bar graph, every family gets 16 kg of rice and 10 kg of wheat;
Cost to the government = 4000 × (16 × 25 + 10 × 18)
⇒ 4000 × 580 = Rs. 2320000
Amount collected from town D = 4000 × (16 × 3 + 10 × 2)
⇒ 4000 × 68 = Rs. 272000
∴ Amount of loss to the government from town D = 2320000 – 272000 = Rs. 2048000Bar Graph and Pie Chart Question 10:
