You can put this solution on YOUR website! Angad is 10 years older than Alex. Mark is 11 years younger than Alex. If the total of their ages is 68, how old is the youngest of them?
Let Alex's age be x
Angad's age will be x+10
Add their ages
Mark's age will be x-11
x+x+10+x-11 =68
3x-1=68
3x=69
x=69/3 = 23
Angad will be 23+10 =33
Mark's age will be 23-11 =12

3M = 36
The youngest, who's Mark, or
