Shopkeeper marked up a pen at certain percentage above its cost price. If marked price of pen is Rs. Y, then find the value of Y?

Show answer & explanation
Correct answer: D
Statement I gives only the markup percentage, so Y cannot be found alone.
Statement II gives enough equations: 0.96Y = 1.08X and Y - X = 28, so Y can be found.
Statement III alone is not enough. But with Statement I, 7Y/9 = P + 70 and Y = 1.8P, so Y can be found.
Therefore either Statement II alone or Statements I and III together are sufficient.
