Let the dividend per share be x, so
n*x=150 and 300*x is what we are looking for
So any value of n or x will give us our answer...

(1) In 1980 the annual dividend on each share of stock X was $0.75.
n*0.75=150.....
Ans is straight 300*0.75=225

(2) In 1979 Mr. Jackson bought a total of 200 shares of stock X.
200*x=150......x=150/200=3/4
Ans is 300*3/4=225
