Question

The ratio of ages of A and B are.
5:4. The sum of ages after 5 years
is 100 years, then ages are.​

Answer 1

Answer:

Let the age of A be 5x and B be 4x. Now ages after 5 years will be 5x+5 and 4x+5

Sum of ages after 5 years= 5x+5+4x+5=100

:. 9x+10=100

:. 9x= 100-10

:. 9x=90

:. X= 90/9= 10

Now A= 5x 5*x= 5*10=50

B=4x =4*x = 4*10 =40

Note ; '*' shows multiplication

Answer 2

Answer:

let the constant be x

let again the ages of A and B be 5x and 4x

therefore after 5 years,

A's age=5x+5

B's age=4x+5

according to question;

(5x+5)+(4x+5)=100

5x+5+4x+5=100

9x+10=100

9x=100-10

9x=90

x=90%9

x=10

s

therefore,A's age=5x

=5*10

=50years

B's age=4x

=4*10

=40years
