1 .If A is 10% greater than B and A = 110,
Than B = 110 * ( 1 – 10% )
= 99
2. If A is greater than B by 10% and B is less than C by 10 than
A = B * ( 1 + 10% )
= 1.1B
And C = B * ( 1 + 10% )
= 1.1B
A is the same as C

✔ 最佳答案
1.B*(1+10%)=AB=110/110%
B=100
2.B*(1+10%)=A
A=1.1B
B*(1-10%)=C
C=0.9B
A is not = C

1
B=110/1.1
=100
2
A=1.1B
C=1.1B(0.9)
=0.99B
A is not the same as C
B=110/1.1
=100
2
A=1.1B
C=1.1B(0.9)
=0.99B
A is not the same as C

1. A = 110
A = B*(1+10%)
SO B = 110 / (1+10%)
= 100
2. By the question,
"If A is greater than B by 10% and B is less than C by 10% than"
your answer is not true,
but if the question is
"If A is greater than B by 10% and B is less than C by 10 than"
A*(1-10%)=C-10
That's not A is the same as C
