Answer:

92776

Step-by-step explanation:

From the given question,

The analysis of the given question can be computed as follows:

I have 5 digits

my two is worth 2000

one of my seven is worth 70

and the other is worth 10 times

as much i.e 10× 70 = 700 700

my other digit is six 6

What number am I?

So, we are expected to look for the summation of all the numbers

i.e 90000 + 2000 + 70 + 700 + 6

= 92776

Thus, the number is 92776
