Answer:
In the year 20 BC
Step-by-step explanation:
Because King Tut died 120 years after King Eros was born,so there are some years no both one in th world.
let some years = z
let King Tut's ages = x
let King Eros's ages =y
so now we know:
x + y = 100
x + y + z =120
from the two,we can know:
z = 20
so there are 20 years after King Eros died.
40BC + 20 years = 20BC
