Question

please solve this question please help

Answer 1

Total butter bought = 5.35 kg =
Total cookies made = 100
Needed butter to make 1 cookie = 255 gram

Total butter needed to make 100 cookies...
= 255 × 100 gram
= 25500 gram
= 25.5 kg

Here, (Total butter bought) < (total butter needed) So; she will need some more butter (and no butter will be left with her)

So, I think this question has some mistakes.

Answer 2

butter she purchases = 5.35 kg

she used up in making 100 cookies = 255g

converte it into kg

that is 255 by 100 = 2.55 kg

butter left with her = total - used up

= 5.35 - 2.55

= 2.8kg
