the ages of A and B are in the ratio of 8 5 if the sum of their ages is

11:8. 5A=8B, A+B=39 SOLVING BOTH EQNS, A=24 AND B=15 YEARS. AFTER 9 YEARS A=24+9=33, B=15+9= 24. SO A:B = 33:24 :: 11:8

ratio of A and B=8:5 and their sum=39=>8x+5x=13x=39=>x=3
therefore ages of A and B is 24 and 15
after 9 years ratio of their ages are 33:24=>11:8

Let us assume the x
8*x+5*x=39
13x=39
X=3
At present their ages are in the ratio A:B=24:15
So after 9 years there should be in the ratio A:B is 33:24

A : B = 8:5
or
A/B=8/5

=> 8X+ 5X = 39
=> 13X= 39 or X=3

therefore => age of A = 8X=24 (current)
and age of B = 5X = 15(current )

ratio after 9 years = (8X +9) : (5X +9)

hence answer = 33 : 24

Information given :

❇The ratio of the ages of a and b is 8:5

❇Sum of the ages of a and b is 39 years.

Solution :

Let the age of a be 8x

Let the age of b be 5x

Sum of the ages = 39

8x+5x = 39

13x = 39

x= 39/13

x= 3

Therefore, the age of the a = 8x = 8 × 3 = 24

The age of the b = 5x = 5 × 3= 15

After 9 years :

Age of a = 24+9 = 33

Age of b = 15 + 9= 24

Ratio of the ages of a and b = 33:24=11:8

the ages of A and B are in the ratio of 8:5.if the sum of their ages is 39 years,what will be the ratio of their ages after 9 years?
