The ratio of cost price to selling price is 5:6. What can be the marked price if a discount of 20% is offered?
a)130
b)135
c)140
d)150
e)160
OE : D

As written this seems unanswerable. We can almost solve if we make two assumptions:
i) Selling price = Marked price - 20%
ii) Each price must be an integer
Using those, we have
Cost = x
Sale = (6/5)x
Marked = (6/5)x / .8 = (3/2)x
x, (6/5)x, and (3/2)x must all be integers by assumption II. With that in mind, either B or D works: we could have Cost = $90, Selling Price = $108, and Marked Price = $135, or we could have Cost = $100, Selling Price = $120, and Marked Price = $150.
