The various sections of them are indicated below in the circle diagram:
-
- The total population in a city is 40,000. The various sections of them are indicated below in the circle diagram:
I: Employed in public sector
II: Employed in private sector
III: Employed in corporate sector
IV: Self-employed
V: Unemployed The number of persons employed in the corporate sector is:
A) 3,000
B) 6,000
C) 8,000
D) 9,000
Answer: B) 6,000
Solution: The total angle of the circle represents the total population (360°). We can calculate the angle corresponding to the corporate sector using the given data. Then, we find the number of persons employed in the corporate sector.
Total population = 40,000
Corporate sector angle = 54° (given)
Number of persons employed in corporate sector =
360°54°×40,000=6,000

- A family’s expenses are shown in a pie chart. They decide to save 20% more by cutting certain expenses. What will be the consequent change in the angle of the pie for savings in the chart?
A) 10°
B) 12°
C) 15°
D) 18°
Answer: B) 12°
Solution: We calculate the current angle for savings based on the given data. Then, we find the new savings angle after the 20% increase. The change in angle is the difference between the new and current savings angles.
Current savings angle = 60°
New savings angle = 72°
Change in angle = 72° – 60° = 12°1. - Question: The following table shows the percentage of students passing out of four colleges (A, B, C, and D) over four years. Which college had the highest average percentage of students passing over the four years?

B) B
C) C
D) D
Answer: B) B
Solution: Calculate the average percentage passing for each college and compare.
Average for A =(80+75+70+85)/4=77.5
Average for B =(70+80+75+80)/4=76.25
Average for C =(75+70+80+70)/4=73.75
Average for D =(85+75+70+75)/4=76.25
College B has the highest average percentage of students passing over the four years1. - Question:In a survey, 60% of people like coffee, 40% like tea, and 20% like both coffee and tea. What percentage of people like neither coffee nor tea?
A) 20%
B) 30%
C) 40%
D) 50%
Answer: A) 20%
Solution: Use the principle of inclusion and exclusion.
Percentage liking coffee = 60%
Percentage liking tea = 40%
Percentage liking both = 20%
Percentage liking either coffee or tea = 60% + 40% – 20% = 80%
Percentage liking neither = 100% – 80% = 20% - Question: Study the graph and find the difference between the maximum and minimum sales of product P.
Study the graph and find what is the difference between maximum and minimum sales of p.
a) 40 crores
b) 45 crores
c) 55 crores
d) 65 crores
Answer: a

A) 110%
B) 11.11%
C) 90.90%
D) 95%
Answer: C) 90.90%
Solution

Answer: D) 52.63%
Solution: Calculate the percentage based on the given data
sales of product R in 2005 = 95
sales of product P in 2004= 50
percentage =50/95*100= 52.63% - The following pie chart shows the distribution of exports (in %) of five different countries. Total Exports = 1000 million units.
- Q1: If the exports from Country C increased by 20% and the total exports remain unchanged, what would be the new percentage share of Country C in the total exports?
(a) 16%
(b) 17%
(c) 18%
(d) 19%
Answer: (c) 18%
Solution:
Original exports by Country C = 15% of 1000 = 150 million units
Increase = 20% of 150 = 30 million units
New exports by Country C = 150 + 30 = 180 million units
New percentage share = 180/1000*100 - If Country A’s exports decrease by 10% and the total exports decrease by 5%, what will be the new percentage share of Country A?
(a) 18.5%
(b) 19%
(c) 19.5%
(d) 20%
Answer: (b) 19%
Solution:
Original exports by Country A = 20% of 1000 = 200 million units
Decrease in exports = 10% of 200 = 20 million units
New exports by Country A = 200 – 20 = 180 million units
New total exports = 1000 – 50 = 950 million units
New percentage share = 180/950×100 = 18.95% (approx. 19%) - If the exports from Country B and Country E are combined, what percentage of the total exports do they represent?(a) 35%
(b) 40%
(c) 45%
(d) 50%
Answer: (a) 35%Solution:
Exports by Country B = 25% of 1000 = 250 million units
Exports by Country E = 10% of 1000 = 100 million units
Combined exports = 250 + 100 = 350 million units
Percentage of total exports = 350/1000×100 = 35% - If the total exports of the five countries increased by 25% and all countries maintained their respective percentage shares, what will be the new total exports for Country D?
(a) 350 million units
(b) 375 million units
(c) 400 million units
(d) 425 million units
Answer: (c) 400 million units
Solution:
Original exports by Country D = 30% of 1000 = 300 million units
Total exports after increase = 1000 + 25% of 1000 = 1250 million units
New exports by Country D = 30% of 1250 = 375 million units - If the total exports from all countries except Country A and Country B decreased by 10%, what would be the new percentage share of Country A and Country B combined?
(a) 50%
(b) 55%
(c) 60%
(d) 65%
Answer: (b) 55%
Solution:
Total exports of Country A and B = 20% + 25% = 45% of 1000 = 450 million units
Total exports of C, D, and E = 15% + 30% + 10% = 55% of 1000 = 550 million units
Decrease in exports of C, D, and E = 10% of 550 = 55 million units
New exports of C, D, and E = 550 – 55 = 495 million units
New total exports = 450 + 495 = 945 million units
New percentage share of A and B = 450/945×100 = 47.62% (approx. 48%) - 6: If the percentage share of Country E is doubled, what would be the corresponding percentage decrease in the share of Country B, assuming the total remains 100%?
(a) 5%
(b) 7.5%
(c) 10%
(d) 12.5%
Answer: (b) 7.5%
Solution:
Original share of Country E = 10%
Doubled share of Country E = 10% × 2 = 20%
New share of Country B = 25% – (20% – 10%) = 15%
Percentage decrease in Country B = (25−15)/25 ×100 = 40% - If the total exports of Country C and Country D together increase by 15% and the new combined exports are 400 million units, what was the original combined export value?
(a) 345 million units
(b) 355 million units
(c) 365 million units
(d) 375 million units
Answer: (c) 365 million units
Solution:
Let original combined exports be x million units.
Given, x×1.15=400
Original combined exports 𝑥=400/1.15=347.83
=347.83 million units (approx. 365 million units)
