# Divide Rs 645 into three parts such that the first part is 2/5 of the second part and the ratio between second part and the third part is 4:3

Since the ratio between second and third part is 4:3,let second and third parts be Rs 4x and Rs 3x respectively
Then the first part=$\frac{2}{5}$ of Rs 4x=Rs$\frac{8x}{5}$
According to the given,
$\Rightarrow \frac{8}{5}x+4x+3x=645$
$\Rightarrow \frac{8x+20x+15x}{5}=645\Rightarrow \frac{43}{5}x=645$
$\Rightarrow x=\frac{645\times5}{43}=75$
$\therefore$ First part=$Rs\frac{8}{5}\times75=Rs120$
Second part=$Rs\, 4\times75=Rs300$
Third part=$Rs\, 3\times75=Rs225$
