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
$\therefore\text{A's share}=\text{Rs. }\frac{3450\times3}{15}$
$=\text{Rs. }230\times3=\text{Rs. }690$
$\text{B's share}=\text{Rs.}\frac{3450\times5}{15}$
$=\text{Rs. }230\times5=\text{Rs. }1150$
$\text{C's }\text{share}=\text{Rs. }\frac{3450\times7}{15}$
$=\text{Rs. }230\times7=\text{Rs. }1610$
