Correct Answer The data either in statement I alone or in statement II alone is sufficient to answer the question.

From statement I:

We can find the number of coins as we have ratio of the coins

From statement II:

By using following equation, we can calculate the number of coins,
⇒ C + (C + 20) = 250
∴ Either of the statements alone is sufficient to answer this question.
