Question 791040: Mira’s mother is presently three times as old as Mira. In 11 years’ time her mother will be twice as old as her mother. How old is Mira now? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Mira’s mother is presently three times as old as Mira
Mother = 3*Mira
In 11 years’ time her mother will be twice as old as Mira.
Mother + 11 = 2(Mira + 11)
Replace Mother with 3*Mira
3*Mira + 11 = 2(Mira + 11)
3*Mira + 11 = 2*Mira + 22
3Mira - 2Mira = 22 - 11
Mira = 11 years old.
Hope this helps.
