x is the cost of the TV

Markup - x * 20/100
Sale price = Markup + cost
= x * 20/100 + x
= 1.2x

M/S = 0.2x/1.2x = 100/6 = 16 2/3

If cost is x...the markup is 20x/100
Which would make the Selling Price x + 20x/100 = 120x/100

So markup as a % of SP =[ (20x/100) / (120x/100) ]*100
= 100/6 = 16 2/3%
