(c) 6.71%
(d) 14%
Check Solution
Ans: (c) 6.71%
Find the percentage increase:
$\text{Percentage Increase} = \frac{\text{875} – \text{820}}{\text{820}} \times 100 = \frac{55}{820} \times 100 \approx 6.71\%$
Q. 2 A company’s annual budget is distributed across five departments:
The total budget is $2,000,000. What is the budget allocated to the Marketing department?

(b) 300,000
(c) 150,000
(d) 250,000
Check Solution
Ans: (b) $300,000
Step 1: Marketing’s percentage share is 15%.
Step 2: Total budget = 2,000,000.
Marketing budget = $15\% \times 2,000,000 = 300,000$
Q. 3 The bar graph below shows the production (in tons) of three crops: Wheat, Rice, and Maize over four years.
What is the average production of Maize over the four years?
(a) 275 tons
(b) 300 tons
(c) 325 tons
(d) 250 tons
Check Solution
Ans: (a) 275 tons
Step 1: Add up the total production of Maize over the years.
- Maize production: 200+250+300+350=1100
Step 2: Calculate the average:
$\text{Average Production} = \frac{\text{Total Production}}{\text{Number of Years}} = \frac{1100}{4} = 275$
Q. 4 A company’s quarterly profits (in $1000) for the years 2022 and 2023 are as follows:
| Quarter | Q1 | Q2 | Q3 | Q4 |
| 2022 Profit | 25 | 30 | 35 | 40 |
| 2023 Profit | 30 | 35 | 40 | 45 |
What is the percentage increase in total annual profit from 2022 to 2023?
(a) 10%
(b) 15%
(c) 20%
(d) 25%
Check Solution
Ans: (b) 15%
Step 1: Calculate the total annual profits for 2022 and 2023.
- 2022: 25+30+35+40=130
- 2023: 30+35+40+45=150
Step 2: Find the percentage increase:
$\text{Percentage Increase} = \frac{\text{150} – \text{130}}{\text{130}} \times 100 = \frac{20}{130} \times 100 = 15.38\%$
Q. 5 A survey shows the percentage distribution of different modes of transport used by people in a city. If the total population surveyed is 20,000, How many people use the train as their primary mode of transport?

(d) 7000
Check Solution
Ans: (b) 5000
Step 1: Total population = 20,000. Train users = 25%.
$\text{Number of Train Users} = 25\% \times 20000 = 0.25 \times 20000 = 5000$

- Company Y: $\frac{1600 – 1400}{1400} \times 100 = \frac{200}{1400} \times 100 = 14.29\%$
- Company Z: $\frac{1500 – 1300}{1300} \times 100 = \frac{200}{1300} \times 100 = 15.38\%$
Step 2: Compare the increases.
Company Z has the highest increase.

Q. 9 The data below shows the distribution of ages in a community:
0–10 years: 100
11–20 years: 200
21–30 years: 150
31–40 years: 250
Above 40 years: 300

(a) 60%
(b) 55%
(c) 70%
(d) 75%
Check Solution
Ans: (b) 55%
