During cooking, a 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?
1,053 grams
1,287 grams
1,300 grams
1,340 grams
To find the weight of the uncooked chicken needed to yield 1,170 grams of cooked chicken, we need to calculate the weight of the uncooked chicken before it lost 10% of its weight.
Let x be the weight of the uncooked chicken.
After cooking, the weight of the chicken is equal to 90% of its original weight:
0.90x = 1,170g
Solving for x:
x = 1,170g / 0.90
x = 1,300g
Therefore, the correct answer is 1,300 grams.
