A. B, and C divide an amount of Rs. 4,200 amongst themselves in the ratio of 7 : 8 : 6 respectively. If an amount of Rs. 200 is added to each of their shares, what will be the new respective ratio of their shares of amount?

Ratio of amounts received by $A, B$ and $C = 7 : 8 : 6$

Sum of ratios $= 7 + 8 + 6 = 21$

=> Sum received by :

$A = \frac{7}{21} \times 4200$ = Rs. $1400$

$B = \frac{8}{21} \times 4200$ = Rs. $1600$

$C = \frac{6}{21} \times 4200$ = Rs. $1200$

On adding Rs. $200$ to the share of each one, the required ratio

$= 1600 : 1800 : 1400$

$= 8 : 9 : 7$

= 8 : 9 : 7
