X-20/100*x=12800
8/10x=12800
X=12800×8/10
X=16000

Answer 2

Answer:

20000

Step-by-step explanation:

Let his salary be = X

money donated = 20%of X = X/5

remaining money = X-X/5 = 4X/5

money deposited in bank = 20%of 4x/5 = 4x/25

remaining money = 12800

X - 4X/5 - 4X/25 = 12800

16X = 12800*25

X = 20000
