Find the present age of Deepak using the following statements: Statement A: Aditi is 6 years younger than Bharat, who is twice the age of Chitra. The present age of Deepak is 50% more than Aditi's age. Four years ago, Bharat's age was three times Deepak's age. Statement B: The age of Bharat is 112.5% more than that of Deepak. The ratio of the present ages of Deepak to Chitra is 8:5. 22 years hence, the ratio of Bharat's age to Chitra's age will be 7:4. Statement C: The sum of the present ages of all four persons is 100 years. The average of the sum of Deepak's and Chitra's present ages is 28 years. The difference between Aditi's and Chitra's present ages is 8 years. Which of the statement(s) alone is/are insufficient to answer the question?
