On a certain assembly line, the rejection rate for Hyundai i10s production was 4 percent, for Hyundai i20s production 8 percent and for the 2 cars combined 7 percent. What was the ratio of Hyundais i10 production?
option
a) 3/1
b) 2/1
c) 1/1
d) 1/2

Read Solution (Total 5)

let the no of i10 cars be x and i20 be y
now th rejcted i10 cars are 4x/100 and i20 cars are 8y/100

and it is given that 4x/100 +8y/100 = 7(x+y)/100
so we get y = 3x
so the ratio is 3:1

let the no of i10 cars be x and i20 be y
now rejction i10 cars are 4x% and i20 cars are 8y%

and it is given that 4x% +8y% = 7(x+y)%
so we get y = 3x
so the ratio is 3:1
