The question is looking for the value of 2c + 5d. Generally, to solve for two variables, we'll need two equations.

Statements (1) and (2) are both insufficient. They give us one equation each. Neither one can be converted into a value for 2c + 5d, so independently, they do not provide a solution.

Taken together, the statements are sufficient. Given the two equations:
c + d = 160, and
5c + 2d = 440
we can solve for c and d, and then find the value of 2c + 5d. Choice (C) is correct.
