Answer:
Step-by-step explanation:
Since we have given that
Fraction of cars were black = 7
Fraction of cars were red = 32/42 7
Fraction of cars were white is given by
1 - (+3) 7
3 = 1
4-7 7
Total number of cars = 210
So, Number of cars were white is given by
4 7 × 210
= 4 x 30
= 120
Hence, there were 120 white cars.
