Qs67 chmura bpp kit

I have few doubts in this question Sales and costs are just increased with relevant percentages but taking into account inflation of 8% in Meghan ...why is that ?? As the description says that they are current prices and cost ?? It's quite confusing ..when they give percentage increase each year and inflation with saying they are current ..means they are in real terms ?? Isn't it So I did according to my understanding first I increased the given current price 115200 *1.05 and then also multiply inflation 1.08^1 ( for first year) Second year I did 120960*1.05 and again inflation multiple with fig 127008*1.08^2 ......148142 and so on My whole answer is totally different and obviously wrong due to this ! I want to know why they don't take Meghan inflation in account If suppose in exam I make this way and I scoring nothing ?? Also I didn't understand the initial investment is not included in year 0 They are taken as present value for 5 years I m doubtful for above
