find percentage

[israel]

Hi helping hand;

I have column"A" with numbers. I am required to add a column "B" showing a
total amount with an addition of 35%.

Now I have to add a column "C" that would give me a number that if you
subtract 40% it will give me the exact number of column "B".

Can anyone help

Thank you

assuming a1 has your value;

in b1: =A1*1.35
in c1: =B1/0.6

Hope I 've got you right
B = A*1.35

B = 0.6 *C

C= 2.25 *A

say A =100
B will be 135
C will be 225
