Question

the rejection rate for audi production was 4 per cent, for mercedes it was 8 per cent and for the 2 cars combined it was 7 per cent. what was the ratio of audi production? a) 4/1 b) 2/1 c) 3/1 d) 7/1

Answer 1

Hello friend,

Given

Rejection rate for Audi = 4%

Rejection rate for Mercedes = 8%

Combined rejection rate = 7%

Consider,

Production rate for Audi = x

Production rate for Mercedes = y

By given condition

4x + 8y = 7(x+y)

Solving this,

3x = y

Hence x/y = ⅓

Also y/x = 3

Thus production ratio of Audi to Mercedes is ⅓ .

Alternatively production ratio of Mercedes to Audi is 3/1

Hope that helped
