Question 7 of 10
7. Question
Directions (5 – 7): Study the following information carefully and answer the questions given below:
There are total 800 students in a class, each student likes one among the three colours viz. Red, Blue and Pink. Respective ratio of boys and girls among them is 9:7. 30% of the boys likes Red colour. Respective ratio of number of boys who like Red colour and number of girls who like Pink colour is 3:2. 25% of the total number of students like Blue colour.

 Find the average of the number of girls who like Red colour and number of girls who like Blue colour.
Correct
Answer: B
Required average = (215 + 45)/2 = 260/2 = 130
Explanation
Total = 800
Number of boys = 800 * (9/16)
= 450
Number of girls = 800 * (7/16)
= 350
Number of boys like Red colour = (30/100) *450
= 135
Number of girls like Pink colour = 135 * (2/3)
= 90
Total number of students like Blue colour = (25/100)*800
= 200
Number of boys like pink colour = (80/100)*200
= 160
Number of boys like Blue colour = 450 – (160+135)
= 450 – 295
= 155
Number of girls like Blue colour = 200 – 155
= 45
Number of girls like Red colour = 350 – (90+45)
= 350 – 135
= 215
Incorrect
Answer: B
Required average = (215 + 45)/2 = 260/2 = 130
Explanation
Total = 800
Number of boys = 800 * (9/16)
= 450
Number of girls = 800 * (7/16)
= 350
Number of boys like Red colour = (30/100) *450
= 135
Number of girls like Pink colour = 135 * (2/3)
= 90
Total number of students like Blue colour = (25/100)*800
= 200
Number of boys like pink colour = (80/100)*200
= 160
Number of boys like Blue colour = 450 – (160+135)
= 450 – 295
= 155
Number of girls like Blue colour = 200 – 155
= 45
Number of girls like Red colour = 350 – (90+45)
= 350 – 135
= 215

Question 8 of 10
8. Question
Directions (810): Study the following information carefully and answer the questions given below:
The following pie chart represents percentage wise distribution of total number of people in a town having different profession.
The following bar graph represents percentage of males among them.
 If number of Engineers in the town is 1200, find the respective ratio of number of male doctors and number of female teachers in the town.
Correct
Answer: D
Total number of people in the town = 100/15 x 1200 = 8000
Number of male doctors in the town = 40/100 x 10/100 x 8000 = 320
Number of female teachers in the town = (100 – 45)/100 x 25/100 x 8000
= 55/100 x 25/100 x 8000
= 1100
Required ratio = 320: 1100 = 16:55
Incorrect
Answer: D
Total number of people in the town = 100/15 x 1200 = 8000
Number of male doctors in the town = 40/100 x 10/100 x 8000 = 320
Number of female teachers in the town = (100 – 45)/100 x 25/100 x 8000
= 55/100 x 25/100 x 8000
= 1100
Required ratio = 320: 1100 = 16:55

Question 9 of 10
9. Question
Directions (810): Study the following information carefully and answer the questions given below:
The following pie chart represents percentage wise distribution of total number of people in a town having different profession.
The following bar graph represents percentage of males among them.
 If number of male teachers in the town is 1350, find the average of the number of doctors, architects and number of people having other professions in the town.
Correct
Answer: A
Let, total number of people in the town = k
45/100 x 25/100 x k = 1350
=> k = 1350 x 100/25 x 100/45
=> k = 12000
Number of doctors in the town = 10/100 x 12000 = 1200
Number of architects in the town = 24/100 x 12000 = 2880
Number of people having other professions in the town = 26/100 x 12000
= 3120
Required average = (1200 + 2880 + 3120)/3
= 7200/3
= 2400
Incorrect
Answer: A
Let, total number of people in the town = k
45/100 x 25/100 x k = 1350
=> k = 1350 x 100/25 x 100/45
=> k = 12000
Number of doctors in the town = 10/100 x 12000 = 1200
Number of architects in the town = 24/100 x 12000 = 2880
Number of people having other professions in the town = 26/100 x 12000
= 3120
Required average = (1200 + 2880 + 3120)/3
= 7200/3
= 2400

10. Question
Directions (810): Study the following information carefully and answer the questions given below:
The following pie chart represents percentage wise distribution of total number of people in a town having different profession.
The following bar graph represents percentage of males among them.
 If total number of people in the town is 20000, find the total number of males in the town.
Correct
Answer: D
Number of male doctors in the town = 40/100 x 10/100 x 20000 = 800
Number of male Engineers in the town = 55/100 x 15/100 x 20000 = 1650
Number of male Teachers in the town = 45/100 x 25/100 x 20000 = 2250
Number of male Architects in the town = 60/100 x 24/100 x 20000 = 2880
Number of males in the town having other professions
= 40/100 x 26/100 x 20000 = 2080
Required sum = 800 + 1650 + 2250 + 2880 + 2080 = 9660
Incorrect
Answer: D
Number of male doctors in the town = 40/100 x 10/100 x 20000 = 800
Number of male Engineers in the town = 55/100 x 15/100 x 20000 = 1650
Number of male Teachers in the town = 45/100 x 25/100 x 20000 = 2250
Number of male Architects in the town = 60/100 x 24/100 x 20000 = 2880
Number of males in the town having other professions
= 40/100 x 26/100 x 20000 = 2080
Required sum = 800 + 1650 + 2250 + 2880 + 2080 = 9660
