(4) Ratio of the amounts received by A, B and C
=7:8:6
Sum of the ratios = 7 + 8 + 6
= 21
Sum received by :
∴ A → $\frac{7}{21}\times 4200=\mathit{R}\mathit{s}.1400$
B →$\frac{8}{21}\times 4200=\mathit{R}\mathit{s}.1600$
C → $\frac{6}{21}\times 4200=\mathit{R}\mathit{s}.1200$
On adding Rs. 200 to the share of each one, the required ratio
= 1600 : 1 800 : 1400
=8 : 9 : 7
