Kaydence's brother is half the father's age, which is 1 / 2 * 60 = 30 years. The total age of Kaydence's father, mother, and brother is 30 + 118 = 148 years. If you add Kaydence's sister's age to the total age of the father, mother, and brother, you get 148 + 40 = 188 years. If everyone's age in the family is 200, then Kaydence's age is 200 - 188 = 12 years old. So the answer is 12. <ibo> Ọ bụrụ na nna Kaydence dị afọ 60, nne ya dị afọ 60 - 2 = afọ 58.
