Answer:

present ages of vatsala and sara 14 years and 10years respectivly After how many years the ratio of their ages will become 5:4?

let us ,

vatsala :14 years

sara :10years

\begin{gathered}14x.10x \\ 4(14 + x)5 \times (10 + x) \\ 56 + 4x = 50 + 5x \\ 56 - 50 = 6 \\ 4x - 5x = x \\ x = 6\end{gathered}

14x.10x

4(14+x)5×(10+x)

56+4x=50+5x

56−50=6

4x−5x=x

x=6
