I think the question should ask "Cost Price" instead of "sale price". Could someone please advise on this ?
Yes you are correct!
I think elimination is the strategy here. Start from C and if the profit is less move down the options and if profit is more, move up the options. The overall profit is $1000
Profit from first car = 11k * 0.1=1100
loss from the second car 9k * 0.1= 900
overall profit =1100-900=$200
Profit from first car= 15k * 0.1= 1500
loss from the second car= 5k * 0.1=500
overall profit = 1500-500=$1000
