Answer:
34 Years.
Step-by-step explanation:
total_age = 33 * 10
one_die = 40-3
two_die = 40-6
three_die = 30 - 9
34 = (total_age - (one_die + two_die + three_die))/7

Answer:
The total age of 10 people 10 years ago was
=10*33=330 years
Now....
After 3 years the total age is=(10*3)+330-40=320 yrs
After another 3 years.... The total age is
=320+(9*3)-40=307
After another 3 years.... The total age was
=307+(8*3)-30=301 yrs
So there are only=(10-3)= 7 peoples left
Still 1 year remaining...
Therfore the total age of 7 peoples in present is
=301+(7*1)=308
Average=308/7=44 years
- You answer is 44 years
Hope this helps you...................
