Question

the ratio of the ages of a and b is 2:3 after 10 years the ratio will be 3:4 find their present ages​

Answer 1

Answer:

Step-by-step explanation:he ratio of the ages of A and B ten years before was 3 : 5.

(2x - 10) / (3x - 10) = 3 / 5

Now solving the equation by cross multiplication

5 ( 2x - 10) = 3 ( 3x - 10)

10x - 50 = 9x - 30

10x - 9x = 50 - 30

x = 20

The rational is 20

hence A's age is 2x = 2 × 20 = 40 years

and B's age is 3x= 3 × 20 = 60 years

Difference in their present ages

B's age - A's age

60 years - 40 years

= 20 years

It means B is older than A by 20 years

Answer difference in their ages will be equal to 20 years

Answer 2

Answer:

20 and 30

Step-by-step explanation:

a/b=2x/3x

2x+10/3x+10=3/4

8x+40=9x+30

x=10
