Answer 1

Step-by-step explanation:

Parking

⬇️

____________________________________________

⬇️ ⬇️ ⬇️

Cars. Motor Cycles. Vans

(50%). (30%). (40)

(i) Calculate the number of motorcycles parked there.

Ans) Let the number of total vehicles be "x"

% of Vans = 100% - (% of cars + % of motorcycles)

=> 100% - ( 50% + 30%)

=> 100% - 80%

= 20%

20% of total vehicles = 40 vans

20% of x = 40

$\frac{20}{100}$ of x = 40

x = 40 × $\frac{100}{20}$

x = 200

Therefore , The number of Motorcycles = 30% of 200

= $\frac{30 \times 20}{100}$

= 60

(ii)If 40 cars left the car park, what percentage of the vehicles parked there were cars?

Ans) Number of cars = 50% of 200

= $\frac{50 \times 200}{100}$

= 100 cars

% of cars = $\frac{number \: of \: cars \: remaining \times 100}{numbers \: of \: vehicles \: remaning}$

= $\frac{60 \times 100}{160}$%

= $\frac{75}{2}$%

= 37.5%

Answer 2

Answer:

Almost all cities prohibit leaving any vehicle parked on a city street too long—often defined as more than 72 hours. Also, check ordinances regarding disabled vehicles (those that are immobilized because they lack an engine, tires, doors, or any other necessary driving equipment).
