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. <hau> Shekaru goma daga yanzu, babba yaro zai zama 20 + 10 = 30 shekara. Idan ɗan fari yana da shekaru 20 a yanzu, na biyu da aka haifa yana da shekaru 20 - 5 = 15 shekaru, shekaru 5 ƙarami fiye da ɗan fari. Na biyu - haifa zai zama 15 + 10 = 25 shekara goma shekaru daga yanzu. Jimlar shekarun na farko da na biyu da aka haifa shekaru 10 daga yanzu zai zama 25 + 30 = 55. Na uku - wanda aka haife shi wanda yake shekaru biyar ya fi ƙarami fiye da na biyu da aka haife shi yana da shekaru 15 - 5 = 10. Shekaru goma daga yanzu ɗan'uwa na uku zai kasance shekaru 10 + 10 = 20. Jimlar shekarun 'yan'uwa uku shekaru goma daga yanzu zai zama 55 + 20 = shekaru 75. Amsar ita ce 75.
