Answer:-

Krishna would have ate 127/128 (99.22%) of the pizza during the week.


Krishna ate half the pizza on Monday.

On Tuesday, he would have ate half of the

remaining pizza i.e. 1/4 of the original pizza.

Similarly, he would have ate 1/8 of

the original pizza on Wednesday and so on for the seven days.

Total pizza Krishna ate during the week is

= 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128

= 127/128
= 99.22% of the original pizza
