Question

the ages of A and B are in ratio of 5:7. four years later the sum of their ages will be 56 years. What are their present ages ?​

Answer 1

Answer:

20 and 28

Step-by-step explanation:

Let the ages of A and B are 5x and 7x

Age of A after 4 years - 5x+4

Age of B after 4 years-7x+4

ATQ

Sum of their ages will be 56 years

5x+4+7x+4 = 56

12x+8=56

12x= 56-8

12x= 48

X= 48/12= 4

Hence , age of A = 5*4= 20 and B = 7*4= 28.
