we have that 80% of A is 1006.2 

this means that 80*A/100 = 1006.2

so 80A = 100620

and A = 100620/80.

hello mikau

sorry your quote not match

just we need to bring back the princple figure by deducting 80% of the total  figure

here  A=?

A*80% =1006.2  so we need common formula to bring back the A value

one time we can figur out  but when ever the values changes  the formula must be correct to caluclate

thanks for your post  i hope some one will help me to find out
