Question

During cooking, chicken loses 10% of its weight due to water loss. In order to obtain 1,170 grams of cooked chicken, how many grams of uncooked chicken must be used?

A: 1,053 grams
B: 1,287 grams
C: 1,300 grams
D: 1,340 grams

Answer 1

Well all you have to do is 1170(1.10) and your answer will be B: 1287 grams

Answer 2

Explanation:

Let weight of the uncooked chicken = x grams

1170 + 10% of x = x

x - 10% of x = 1170

`x-0.1x=1170\\0.9x=1170\\\\x=(1170)/(0.9)\\\\x=(1170*10)/(0.9*10)\\\\x=(11700)/(9)\\\\x=1300grams\\`
