If the elder child is 20 years old now, the second born is 20 - 5 = 15 years old, 5 years younger than the firstborn. The second - born will be 15 + 10 = 25 years old ten years from now. The total age of the first and second - born 10 years from now will be 25 + 30 = 55. The third - born who is five years younger than the second born is 15 - 5 = 10 years old. The third sibling's age ten years from now will be 10 + 10 = 20 years old. The total age of the three siblings ten years from now will be 55 + 20 = 75 years. So, the answer is 75.
