Query about Question 6 from "Timed Quant Practice - Hard Section 2 Sample #1" [8952]

if profit markup is 100%, isnt the sellping price then 20?

I think the question is wrong as is. It should say that the profit markup is 100 \% of the cost price.

Once we establish that, then yes, you’re right

And fixed.
