If counted in pairs,one will remain..If counted in threes, two will re...
To find the number of eggs in the basket, we need to solve a series of modular equations based on the conditions provided. Let's break down the problem:

Understanding the Conditions
- If counted in pairs (2), one will remain:
**Equation:** \( x \equiv 1 \mod 2 \)
- If counted in threes (3), two will remain:
**Equation:** \( x \equiv 2 \mod 3 \)
- If counted in fours (4), three will remain:
**Equation:** \( x \equiv 3 \mod 4 \)
- If counted in fives (5), four will remain:
**Equation:** \( x \equiv 4 \mod 5 \)
- If counted in sixes (6), five will remain:
**Equation:** \( x \equiv 5 \mod 6 \)
- If counted in sevens (7), nothing will remain:
**Equation:** \( x \equiv 0 \mod 7 \)

Finding a Common Solution
These conditions can be rephrased as follows:
- \( x = 2k + 1 \) for some integer \( k \) (from the first condition).
- \( x = 3m + 2 \) (second condition).
- \( x = 4n + 3 \) (third condition).
- \( x = 5p + 4 \) (fourth condition).
- \( x = 6q + 5 \) (fifth condition).
- \( x = 7r \) (sixth condition).
By analyzing the equations, we see that for the first five conditions, \( x \) is always one less than the base number (2, 3, 4, 5, 6). Thus, \( x + 1 \) must be a multiple of 2, 3, 4, 5, and 6. The least common multiple (LCM) of these numbers is 60. Therefore:
- \( x + 1 = 60k \) for some integer \( k \)
- Thus, \( x = 60k - 1 \)

Considering the Last Condition
For the seventh condition \( x \equiv 0 \mod 7 \):
- Substitute \( x = 60k - 1 \) into this equation:
\( 60k - 1 \equiv 0 \mod 7 \)
or \( 60k \equiv 1 \mod 7 \).
- Calculate \( 60 \mod 7 \):
\( 60 \equiv 4 \mod 7 \). Thus:
\( 4k \equiv 1 \mod 7 \).
The multiplicative inverse of 4 modulo 7 is 2, so multiply both sides by 2:
- \( k \equiv 2 \mod 7 \)
- Therefore, \( k = 7m + 2 \) for some integer \( m \).

Final Calculation
Substitute back to find \( x \):
- \( x = 60(7m + 2) - 1 = 420m + 119 \).
