answer is 11 if I have understood the question correctly.

assume he ate x pieces on day 1. Everyday he eats 7 more than the previous.

x+(x+7)+(x+14)+(x+21)+(x+28)+(x+35)=125
therefore x=11

Hope the item was not prepared on day1 and got spoilt , the second day itselfWink

X + (X+7) + (X+14) + (X+21) + (X+28) = 125

5X + 70 = 125

5X = 125 - 70 = 55

So, X = 11

Giri answer sarithan aana athu epdi 6 days potte??
appo 6X + 105 = 125 thaane varum??
5 days thane kanakku??

1st Day     97 hot dogs
2nd Day   97+7=104
3rd Day  104+7 = 111
4th day    111+7 = 118
5th Day    118 +7 = 125
