[Huang Hsin-Yi]

49.If the total price of n equally priced shares of a certain stock was $12000, what was the price per share of the stock?

(1) If the price per share of the stock had been $1 more, the total price of the n shares would have been $300 more
(2)If the price per share of share of the stock had been $2 less , the total price of the n shares would have been 5 % less

Ans:D

想請教劃線部份的中文意思?

[kieth]

應該是指：每股股價相等的一隻股票總股價是12000

[Huang Hsin-Yi]

再請教選項(1)(2)式子該怎樣列?

[kieth]

1 [(12000/n)+1]*n=12000+300，可解出共有多少share
2 [(12000/n)-2]*n=12000*0.95，一樣可解出有多少share
