If you write all the whole numbers from 1 to 500 in a row, what will be the 500th digit?
1 answer:
Answer:
Option A.
Step-by-step explanation:
We need to find the 500th digit if we write all the whole numbers from 1 to 500 in a row.
Single digit numbers are : 1-9 = 9 number = 9 digits
Double digit numbers are : 10-99 = 90 number = 180 digits
Total digits form 1 to 99 = 9+180 = 189
Now,
It means we have write 311 more digits.
After 99 we have 3 digit number.
311 is not divisible by 3. The number immediate before 311 which is divisible by 3 is 309.
It means the required digit is 2nd digit of 104th number after 99.
104th number after 99 is 203 and second digit of 203 is 0.
Therefore, the correct option is A.

Answer:
in order by function: 0.6, 8, 7/3, 2, 1/2
Step-by-step explanation:
The functions are given in the form ...
f(x) = a·b^x
The "b" value is the value immediately to the left of the exponent. (It's not rocket science; it's pattern matching.) Note that the minus sign in g(x) is part of 'a', not part of 'b'.
From the top-down, the functions listed on the left have the b-values shown above.
