A scientist named Bob was exposed to some radiations which caused him to oge backwards after he turned 40. Four years la current age and his daughter Bella's age are in the ratio 3:1.
Determine the ratio of Bob's and Bella's age four years before Bob turned 40
Answers
x= Bella's age
Four years later Bella's age and his daughter Bella's age are in the ratio 3:1.
= 36 : x
x= 36/3 = 12
ratio of Bob's and Bella's age four years before Bob turned 40
bobs age = 36
Bella's age = 8
ratio = 36:8 = 9:2
Given : A scientist named Bob was exposed to some radiation which caused him to age backward after he turned 40.
Four years later, his current age and his daughter Bella's age are in the ratio 3:1.
Determine the ratio of Bob's and Bella's age four years before Bob turned 40.
Solution:
Age of Bob = 40
Age of Daughter = D years
some radiation which caused him to age backward after he turned 40.
so Age of Scientist after 4 years = 40 - 4 = 36 years
Daughter Age = D + 4 Years
36 /( D + 4) = 3/1
=> D + 4 = 12
=> D = 8
Four year before 40 also
Age of Bob = 40 - 4 = 36 years
Age of Daughter = 8 - 4 = 4 Years
Ratio 36 : 4
= 9 : 1
ratio of Bob's and Alice's age four years before Bob turned 40. is 9 : 1
