Quantity A: The two-digit integer that equals twice the sum of its digits
Quantity B: 14
选项
A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案
A
解析
Quantity A的含义是:等于它自己数位之和的2倍的两位整数。则设Quantity A的个位数字是y,十位数字是x,得到10x+y=2(x+y),可以将其化简为8x=y。因为z只能取1到9的整数,y只能取0到9的整数,所以,x只能取1,得出y=8。那么两位数
=18,大于14。所以答案为A选项。
