Ans: (d) -10%

Sales employees in 2021 = 200

Sales employees in 20221 = 180

$\text{Percentage Increase} = \frac{\text{180} – \text{200}}{\text{200}} \times 100 = \frac{-20}{200} \times 100 = {-10}\%$

Remember that percentage si caulated with reference to intial value (200 in this case) and not final value (180)

Ans: (c) 6.71%

Total numbe rof emplyees in 2021 = 820

Total number of employees in 2023 = 875

Find the percentage increase:

$\text{Percentage Increase} = \frac{\text{875} – \text{820}}{\text{820}} \times 100 = \frac{55}{820} \times 100 \approx 6.71\%$

Ans: (b) $300,000

Step 1: Add up the total production of Maize over the years.

• Maize production: 200+250+300+350=1100

Ans: (c) 25%

Step 1: Wheat production in 2020 = 400

Step 2: Wheat production in 2023 = 500

Ans: (a) 130,000

Calculate the total annual profits for 2022

2022: 25+30+35+40=130

Since units is in 1000$, then total profit is 130*1000 = \$130,000

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:

$\text{Percentage Increase} = \frac{\text{150} – \text{130}}{\text{130}} \times 100 = \frac{20}{130} \times 100 = 15.38\%$

Ans: (a) $610,000

Step 1: Add the sales for all cities in March:

• 140+170+120+95+85=610 (in $1000)

Ans: (b) 3

City A, B and C saw increase in sales while D and E are seeing decrease in the sales

Ans: (c) Company Z

Step 1: Calculate percentage increases for each company:

• Company X: $\frac{1700 – 1500}{1500} \times 100 = \frac{200}{1500} \times 100 = 13.33\%$
• 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.

Ans: (d) Can’t say, total cost is increasing but we don’t know the unit productiont trend

Ans: (c) 2020-21

Calculate revenue change for every year. Highest jump is 2020-21 = (70-60)/60*100 = 16.7%

Ans: (b) 11-30 years

No of people in 11-30 years category = 200 + 150 =350 which is more than any other category given

Ans: (b) 55%

Step 1: Add the population aged 31 or above:

• 250+300=550. Total population = 100+200+150+250+300=1000

Step 2: Calculate the percentage:

$\text{Percentage} = \frac{550}{1000} \times 100 = 55\%$

Ans: (a) 1240
