Directions For Questions

Direction: Study the following table carefully and answer the given questions accordingly.

The given table shows the number of laptops sold by different companies during 5 years.

Years → Brand ↓	2017	2018	2019	2020	2021

...view full instructions

The number of laptops sold by HP in 2019 is what percentage more than the number of laptops sold by Dell in 2021?

\(\frac{50}{3}\%\)

20%

\(\frac{40}{3}\%\)

15%

Solution

Given:

The number of laptops sold by HP in 2019 = 90

The number of laptops sold by Dell in 2021 = 75

Calculation:

The difference in the number of laptops sold = 90 - 75

⇒ The difference in the number of laptops sold = 15

Required percentage \(= \frac{15}{75} × 100\)

⇒ Required percentage = 20%

∴ The number of laptops sold by HP in 2019 is 20% more than the number of laptops sold by Dell in 2021.

Given:

The number of laptops sold by Lenovo in different years is 90, 80, 90, 90, 100.

Formula:

Average \(= \frac{The sum of all observations}{Number of observations}\)

Calculation:

Required Average \(= \frac{90 + 80 + 90 + 90 + 100}{5}\)

\(= \frac{450}{5}\)

⇒ Average = 90

∴ The average number of laptops sold by Lenovo during all years is 90.

In which year, the total number of laptops sold was the highest?

2018

2019

2020

2021

Solution

The total number of laptops sold in 2017 = 110 + 75 + 90 + 75

= 350

The total number of laptops sold in 2018 = 105 + 95 + 80 + 70

= 350

The total number of laptops sold in 2019 = 90 + 110 + 90 + 110

= 400

The total number of laptops sold in 2020 = 85 + 95 + 90 + 80

= 350

The total number of laptops sold in 2021 = 110 + 75 + 100 + 65

= 350

∴ The total number of laptops sold was highest in 2019.

The total number of laptops sold by HP in 2019 and 2020 = 90 + 85

= 175

Required ratio = 170 ∶ 175

⇒ Required ratio = 34 ∶ 35

∴ Required ratio is 34 ∶ 35.
