Answer 1

Step-by-step explanation:

$\huge\underline{\overline{\mid{\bold{\purple{AnsWer}}\mid}}}$

$\displaystyle \sf \longrightarrow Ratio = 8x:11x$

$\tt : \implies \: 8x = 72 \\ \\ \tt : \implies \: x \: = 9 \: \:$

$\displaystyle \sf \longrightarrow white cars = 11 ×9$

$\displaystyle \sf \longrightarrow white cars = 99$

$\displaystyle \sf \longrightarrow total cars = 99+72$

$\displaystyle \sf \longrightarrow total cars = 171$

Answer 2

Answer:

Total number of cars=171

number of red cars=72
