১০০ এর ৮%, ৭.৫ হইল কেমনে ভাই!!!??

Sir 100 rupay me ager15%discount dete hai to 85 rupay ata hai lekin mai ye chahta hu 15% discount du lekin 15% Ka vat lu taki 85 rupay me 15 rupay jo discount diya hu to 15 rupay ka vat 85 rupay me jod lu. Talk 85 rupay aur 15 rupay ka vat 2.25 rupay 15% I hisab se jod kr 85+2.25=87.25 rupay ho jaye.plese koi formula btaiye please .bahut presan hu please.

If you know that 20% equals 310 how can I work out the net amount?

If we have net sales including vat of 2000 and the subtraction of 15% vat is 1700 as sales price so if we put 15% on 1700 we get 255 as vat but when we subtract 15% vat of 2000 we get 1700 and 1700+ 255 is equal to 1955 so where has the 45 rupees gone please explain.
