Um where the problem or number?
1+2+3= 6 (even)
2+3+4= 9 (odd)
it can be both
The answer is 260 have a good day.
I love it when people ask me these questions.
Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
Hope This Helps You!
