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=frac25 of Rs 4x=Rsfrac8x5
According to the given,
Rightarrow frac85x+4x+3x=645
Rightarrow frac8x+20x+15x5=645Rightarrow frac435x=645
Rightarrow x=frac645 imes543=75
herefore First part=Rsfrac85 imes75=Rs120
    Second part=Rs, 4 imes75=Rs300
    Third part=Rs, 3 imes75=Rs225
