Worked Solution & Example Answer:A delivery company has a total of 160 cars and vans - Edexcel - GCSE Maths - Question 4 - 2022 - Paper 1
Step 1
Determine the number of cars and vans
Answer
Given the ratio of cars to vans is 3:7, the total parts are:
- Cars: 3 parts
- Vans: 7 parts
Therefore, for a total of 10 parts, we can find the number of each:
- Number of cars = ( \frac{3}{10} \times 160 = 48 )
- Number of vans = ( \frac{7}{10} \times 160 = 112 )
Step 2
Step 3
Step 4
Determine the number of cars using petrol
Answer
Now we can find the remaining cars that use petrol:
- Total cars = 48
- Cars using electricity = 6
- Cars using diesel = 12
- Cars using petrol = Total cars - (Cars using electricity + Cars using diesel)
This results in:
- Cars using petrol = ( 48 - (6 + 12) = 30 )
