Mrs. Jenson had her first child at the age of 23, another a year later, and the third a year after that. How old will she be when her age is the same as the sum of her childrens' ages? Thanks.
Let the oldest =a Middle child =a-1 Youngest child =a-2 a + a -1 + a - 2=23+a 2a =26 a=13 - The oldest child Next =12- The middle child next =11- The youngest child 23 + 13 =36 - The mother's age
