B Correct answer
Explanation

After 20% charity deduction, 80% of profit is distributed in ratio 7:5:6. Yuvaraj's share is 5/(7+5+6) of 80%. Let P be total profit: (5/18) × 0.8P = 30000, so P = 30000 × 18/(5 × 0.8) = 30000 × 4.5 = 135000. The key is understanding that only 80% is shared, not the full profit.
