age of zena will be twice the age of sele after 6 years.total number of their age is 42 now.find out the age of Sena now
s+6 = 2(a+6)
a+s = 42
Sena is 30
To determine the age of Sena now, we can let x be the current age of Sena.
According to the given information, the age of Zena will be twice the age of Sena after 6 years. So, after 6 years, Zena's age will be x + 6, and Sena's age will be x + 6 as well.
The total number of their ages is currently 42, so we can set up an equation:
x + (x + 6) = 42
Combining like terms:
2x + 6 = 42
Subtracting 6 from both sides:
2x = 36
Dividing both sides by 2:
x = 18
Therefore, the age of Sena now is 18 years old.
