A just gives one eqn to solve for the prices of Donut and cupcake.
20D = 30C-1
B gives another eqn to solve for the prices:
D+C=0.7

A & B together can be used to solve for D & C.
Now,
6=xD+yC.

Still be left with two unknowns. So, both may be insufficient.

It should be E. Even after combining the statements, number is unknown.

OA is E. I thought question stem says D+C=6. actually i mistook it as 6 dollars for 1 doughnut and 1 cake instead of 1 kind.
