Explanation

Let x = 0.125125125...

Multiply x by 1000:

1000x = 125.125125...

Subtract x from 1000x:

999x = 125

Divide by 999:

x = 125/999

Explanation

(1+1/x) (1+1/x+1) (1+1/x+2) (1 + 1/x + 3)

Simplify each term:

(x+1)/x * (x+2)/x * (x+3)/x * (x+4)/x

Multiply the numerators and denominators:

(x+1)(x+2)(x+3)(x+4) / x^4

Expand the numerator:

x^4 + 10x^3 + 35x^2 + 50x + 24

Divide by x^4:

1 + 10/x + 35/x^2 + 50/x^3 + 24/x^4

Now, simplify the expression:

Combine like terms:

x + 4/x

Explanation

If 4 is removed, the sum of the remaining numbers is 0 + 2 + 5 + 9 = 16.

The average remains the same, 16/4 = 4.

Explanation

Sum of the ages of 3 friends =3×23= 69 years

Sum of the ages of 4 friends =4×23= 92 years

∴ Age of 4th friend = 92 years - 69 years = 23 years.
