Question

the age of A is five years more than that of B. five years ago the ratio of their ages was 3:2 find their present age
​

Answer 1

Age of B = X

Age of A= X+5

5 years ag , the ratio was 2:3 ( I reversed the ratio cuz I took B first)

2/3 = X/X+5

Now by cross multiplying

2(X+5)=3X

=> 2X + 10 = 3X

=> X = 10

Which means before 5 years , the age of B was 10 and the age of A was 15 and now , which is 5 years later the age of B is 15 and age of A is 20

Hope this answer helps you.

Answer 2

A = x+5

B=x

5 years ago, the ratio was 3:2

3/2=x/x+5
Now by cross multiplication
2(x+5)=3x
2x+10=3x
x=10
A=10
B=x+5
B=10+5
B=15
