A man gave 20% of his money to his son, 30% of the remainder to his daughter, and 10% of what then remained to charity. He was left with Rs. 10080. Find the total money.
Correct Answer: Option B
Explanation:
Let total = T. Son 20%, left 80%. Daughter 30% of 80% = 24% of T, left 56%. Charity 10% of 56% = 5.6% of T, left 50.4% = 10080 → T = 10080/0.504 = 20000.
