+59 Ten years ago, the sum of the ages of Ted and his twin brother Todd was 22. How old is Ted now?
+4622 Ted=t
Todd=d
Solution 1: Thus, we have (t-10)+(d-10)=22, t+d=22+20, t+d=42. Since they are twin brothers, Ted is 42/2=21 years old.
Solution 2: Ten years ago, each of them was 22/2=11 years old. Thus, Ted is 11+10=21 years old/
+37153 Since they are both the same age let's say T = Ted's age now (what we are looking for...also Todd's age)
Ten years ago 2(T-10) = 22
T-10 =11
T = 21 Ted's (and Todd's) age now
Ten years ago, the sum of the ages of Ted and his twin brother Todd was 22. How old is Ted now?
Ted and Todd are twins, thus they are the same age.
When the sum of their ages was 22, each brother was 11.
Move forward ten years (i.e., 11 + 10), and Ted is now 21. So is Todd, if it matters.
