Question

the ratio of Ages of Anu and Renu is 5.7. Four later, the ratio of the Year ages will be 3:4 .find their present ages.​

Answer 1

Let present ages be 5x and 7x of anu nad renu
After 4 years
Anu's age= 5x+4
Renu's age= 7x+4
ATQ,
(5x+4):(7x+4)=3:4
=> 4(5x+4)=3(7x+4)
=> 20x+16=21x+ 12
=>21x-20x=16-12
X= 4

Anu presnt age is 20
Renu present age is 28

Answer 2

Step-by-step explanation:

Let their ages be 5x and 7x

5x-4/7x-4=3/4

20x-16=21x-12

21x-20x=16-12

x=4

Age of anu:20

Age of renu:28
