Question
Divide $Rs. 3450$ among $A, B$ and $C$ in the ratio $3 : 5 : 7.$

Answer

Total amount $= Rs. 3450$
Ratio in $A, B$ and $C$ shares $= 3 : 5 : 7$
Sum of share $= 3 + 5 + 7 = 15$
$\therefore\text{A's share}=\text{Rs. }\frac{3450\times3}{15}$
$=\text{Rs. }230\times3=\text{Rs. }690$
$\text{B's share}=\text{Rs.}\frac{3450\times5}{15}$
$=\text{Rs. }230\times5=\text{Rs. }1150$
$\text{C's }\text{share}=\text{Rs. }\frac{3450\times7}{15}$
$=\text{Rs. }230\times7=\text{Rs. }1610$
