Question

this is very difficult question for me answer it plzz​

Answer 1

Explanation:

we should never count the balance because

for example we have 20

we spent= 1

balance =19

next day we again spent 1

balance =18

then 19 +18=37

we should do 1+1+18=20.

likewise, 0+20+15+9+6 = 50

not 30+15+6+0=51

that's it
