✔ 最佳答案
C is less than B by 10%姐係c比b少10%
應該係
c=bx(1-10%)
=0.9b

有錯
If A is greater than B by 10 % and C is less than B by 10%
(如果a是大過b10%和c是小過b10%)
所以
a=bx(1+10%)
=1.1b
(問題出現了你錯在下)
c =Bx(1+10%) <----------錯
=1.1B <----------錯
正確為:
c =bx(1-10%)
=0.9b
因問題問
C is less than B by 10%(c是小過b10%)而不是
C is ｍｏｒｅ than B by 10%,如果是C is ｍｏｒｅ than B by 10%你便沒有錯

If A is greater(大於) than B by 10 % and C is less (小於)than B by 10% than
A=Bx(1+10%)
=1.1B
and C =Bx( 1 -10%)
=0.9B
A is not same as C.
A=Bx(1+10%)
=1.1B
and C =Bx( 1 -10%)
=0.9B
A is not same as C.

If A is greater than B by 10 %
即A > B
and C is less than B by 10% than
即B>C
總結
A>B>C
A和C不可能相同
A is greater than B by 10 %
A=Bx(1+10%)
=1.1B
C is less than B by 10%
C=Bx(1-10%)
=0.9B
A=1.1B
C=0.9B
即A > B
and C is less than B by 10% than
即B>C
總結
A>B>C
A和C不可能相同
A is greater than B by 10 %
A=Bx(1+10%)
=1.1B
C is less than B by 10%
C=Bx(1-10%)
=0.9B
A=1.1B
C=0.9B
