Explanation:
Answer: 69kg
Explanation:
Let the total weight of the woman be represented by x. Based on the information given, we can derive an equation which will be:
55% of x = 38kg
55/100 × x = 38kg
0.55 × x = 38kg
0.55x = 38kg
Divide through by 0.55
x = 38kg/0.55
x = 69.09099
x = 69kg
Therefore, the woman's total weight is 69kg.

Chorionic villus sampling test is used to determine the genetic disorder or chromosomal disorder in a fetus. Chorionic villus test is done by the PCR or by FISH. This test can take place usually performed in 10 to 12 weeks gestation i.e. first trimester, before amniocentesis. Chorionic villus can be removed by a needle. Pregnancy loss in CVS (Chorionic villus sampling) is 2-3 percent. So it is highly accurate.
