呢題數學題有咩錯?!`

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.

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

B = A/1+10%

and C =90%/100

=1.1C

呢題數學題有咩錯::
比正確答案我
(用中文答,THZZ=])

If A is greater than B by 10 % and C is less than B by 10% than
A=Bx(1+10%)
=1.1B
and c =Bx(1+10%)<------------------it is wrong

corrections:

C = Bx(1 - 10%)

C = 0.9B
