The ratio between the ages of A and B after five years will be 4:5. Sum of their present
ages is 17 years. What is A's present age ?​

Answer 1

Answer:

7 years

Step-by-step explanation:

If the sum of their age = 17 then after 5 years it will be 27 and their age will be 4:5

So after 5 years their age will be

4x + 5x = 27

x = 27/9

x = 3

So A's age after 5 years is 4x = 4 × 3 = 12

So A's current age is 12 - 5 = 7 years
