Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease

Option B
Answer:
30 years
Step-by-step explanation:
Forming Algebraic expressions and solving them to find the age.
Ratio of age of mother and daughter = 5 : 3
Age of mother = 5x
Age of daughter = 3x
It is given that mother's age is 50 years.
⇒ 5x = 50
Divide both sides by 5.
x = 50÷5
x = 10
Daughter's age = 3x
= 3*10
= 30 years
