Find Missing Digits: Complete ??98 Between 7,001 and 8,100

Question

Insert the missing digits in order to obtain a number that correctly lies within the given range:

7,001 < ??98 < 8,100

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify possible candidates for the missing digits.
  • Step 2: Substitute digits from the choices and check their suitability by comparing with given boundaries.

Now, let's work through each step:
Step 1: We need to find a number of the form ??98 ??98 and check possible combinations for the '?'. Given the choices, we'll consider 7,001 to 8,100 as the interval.
Step 2: Evaluate: the number should start with either 7 or 8 because 7,001 is above 7,000. Checking, 7,198 7,198 and 8,098 8,098 are obvious boundaries and choices.

Substitute option '8,0' leading to 8,098 8,098 which satisfies:
7,001<8,098<8,100 7,001 < 8,098 < 8,100 .

Therefore, the correct missing digits are 8,0 8,0 .

Answer

8,0 8,0
