$\huge\boxed{\fcolorbox{black}{pink}{Answer}}$

Let ,

No of Silver Car's be 7x

No of white Car's be 4x

No of black car's be 2x

☆____According to the question

=> 7x + 4x + 2x = 1300

=> 13x = 1300

=> x = 100

Then,

Silver cars = 7 × 100 = 700

White cars = 4 × 100 = 400

Black cars = 2 × 100 = 200
