Fundamentals: Binding energy method

A reaction is shown: P + Q = W + X . The total binding energy of W and X is 40 MeV. Binding energy of P is 20 Mev . The energy released is 7 Mev. What is binding energy of Q?
Binding energy of P + Q is 7 Mev less than that of W + X , hence BE of P + Q = 33 Mev. Be of Q is 33 - 20 = 13 Mev.
