Answer:
Fraction of cloth that turns green =
Step-by-step explanation:
Let total cloth be of length = 1 unit
Given of it is dipped in blue dye.
Fraction which is not dipped in blue is given as:
⇒
Taking LCD to subtract fractions.
⇒
⇒
She dips in yellow.
Comparing the fraction dipped in yellow which is and fraction which is not dipped in blue i.e.
Taking LCD between 8 and 20 = 40
We have:
Thus, we can say
Since , so the part dipped in yellow will also cover some part which is blue.
Thus, fraction dipped in yellow and blue which turns green will be given as:
⇒
Subtracting by taking LCD =40.
