Let, the present age of Mira is x
so her sons' present age is x/30
18 year later, the age of Mira will x + 18 and the age of her son will (x/30) + 18
Now, according to the question,
x + 18 = 3{(x/30) + 18}
or, x + 18 = (x/10) + 54
or, 10x + 180 = x + 540 [Multiplying both sides by 10]
or, 10x - x = 540 - 180
or, 9x = 360
or, x = 360/9
or, x = 40.
Ans: The present age of Mira is 40.
