take father's age as x
if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80
accordingly the equation will be 2x=80
x=40
given that ,
son is 1/4 th of his father
hence ,
son = 1/4×(x)
I.e, 1/4×40 =10

For this case we must calculate the values of the unknowns.
We have then:
is 3,000 times greater than
We have the following equation:
From here, we clear the value of x:
Then, on the other hand we have:
"and is _____ times greater than 1.38 × 101"
That is, we have the following equation:
The value of y is:
Answer:
6.9 × 105 is 3,000 times greater than 2.3 × 102 and is 50000 times greater than 1.38 × 101.
