Answer 2

Answer:

Amu=25 and Raju=25

Step-by-step explanation:

Ratio of Amu and Raju's present age= 4:5

Let Amu and Raju's present ages be 4$x$ and 5$x$ respectively

After 10 years ratio of their ages = 6:7

After 10 years let Amu and Raju's ages be $4x + 10$ and $5x + 10$ respectively

$((4x+10)/(5x+10))=6/7\\6(5x+10)=7(4x+10)$

$30x+60=28x+70\\30x-28x=70-60\\2x=10\\x=5$

Amu's present age = $4x$

                                = 4×5

                                = 20

Raju's present age  = $5x$

                                = 5×5

                                = 25

Therefore, Amu's present age is 20 and Raju's present age is 25.
