as N/E = .25, N = .25 * E

-> E = 60,800 as 15,200 = .25 * E

as E/A = .40, E = .40 * A

-> A = 152,000 as 60,800 = .40 * A

as A - D = E, - D = E - A

as - D = - 91,200, D = 91,200

-> D/A = 91,200 / 152,000 = .60

easier way:

A-D=E , divide each term by A

A/A - D/A = E/A

1 - D/A = .40

1 - .40 = D/A

D/A = .60

N never entered the picture.
