(1 – 1.25)N = 1
Simplify to get: -0.25N = 1
Rewrite as (-1/4)N = 1
Multiply both sides by -4 to get: N = -4

Answer: C

\((1 – 1.25)N = 1\) --> \((-0.25)N = 1\) --> \(N = \frac{1}{-0.25}\) --> \(N = \frac{1}{-1/4}\) --> \(N = -4\)
Answer choice C.

We need to determine the value of N in the equation (1 – 1.25)N = 1.

(1 – 1.25)N = 1

(-0.25)N = 1

(-1/4)N = 1

N = -4

Answer: C

(1 – 1.25)N = 1

Or (\(1\) – \(\frac{5}{4}\))N = \(1\)

Or \(\frac{-1}{4}\)N = \(1\)

So, N = - 4

Hence answer will definitely be (C)

1-1.25 = -.25
n/-4 = 1
cross multiply and you get n = -4

As we are deducting 1.25 from 1, ultimate result will be negative. Eliminate D and E. -0..25 is equivalent to 1/4. so ultimate result will be -4.

Thus the best answer is Option C.

In this case we have 1-(1.25 is 5/4), so that's going to be -1/4.

the correct answer choice is C.
