Answer 1

Given:

✰ In a month there has been an increase of 4.9% of stolen cars.

✰ 546 cars were stolen last month.

To Find:

✠ Number of cars stolen this month.

Solution:

❖ Let's understand the concept first! In a month there has been an increase of 4.9% of stolen cars. First we will convert this percentage form of an increase in stolen cars to simple decimal form. After that we will increase last month's car by the simple decimal form to get the number of cars stolen this month.

There has been an increase of 4.9% of stolen cars.

From percentage to decimal.

⟹ Increase in number of stolen cars = 4.9% of 546

⟹ Increase in number of stolen cars = 4.9/100 × 546

⟹ Increase in number of stolen cars = 49/1000 × 546

⟹ Increase in number of stolen cars = 26754/1000

⟹ Increase in number of stolen cars = 27 ( approx )

➤ Number of cars stolen this month = Number of cars stolen last month + Increase in number of stolen cars

➤ Number of cars stolen this month = 546 + 27

➤ Number of cars stolen this month = 573

∴ The number of cars stolen this month = 573 cars
