[計量] 請教 BB p.161 No.30
Two tanks, X and Y, are filled to capacity with jet
fuel. Tank X holds 600 gallons more than tank Y.
If 100 gallons of fuel were to be pumped from each
tank, tank X would then contain 3 times as much
fuel as tank Y. What is the total number of gallons
of fuel in the two full tanks?
(A)1400 (B)1200 (C)1000 (D)900 (E)800
--------
答案是給(A)
可是我對題目的了解怎麼算都是(B)
我猜可能是我對題目有誤解了
可否請各位大大幫我解惑一下??
感恩XD
