Answer
Answer (as printed): C
Explanation
$A: B=3: 7, B: C=6: 5=\left(6 \times \frac{7}{6}\right):\left(5 \times \frac{7}{6}\right)=7: \frac{35}{6}$. $A: B: C=3: 7: \frac{35}{6}=18: 42: 35$. Sum of ratio terms $=(18+42+35)=95$. $\therefore$ B's share $=₹\left(33630 \times \frac{42}{95}\right)=₹ 14868$.
