k = 60125 * 10^-3 = 60.125

(6*10^4 + 0*10^3 + 1*10^2 + 2 *10^1 + 5 * 10^0) * 10^-3 = 60.125

Hence (A)

please correct me if i am wrong

Given: k/60125 = 0.001
Rewrite right side as fraction: k/60125 = 1/1000
Cross multiply to get: (1000)(k) = (1)(60125)
Divide both sides by 1000 to get: k = 60125/1000 [there are 3 zeros in 1000, so when we divide by 1000, we move the decimal point 3 SPACES TO THE LEFT]
We get: k = 60.125

Cheers,
Brent

$$\frac{k}{60125}$$ = 0.001
k = 60125 x 0.001 = 60.125

Units digit is 0.

$$\frac{k}{60125} = 0.001$$

$$\frac{k}{60125} = \frac{1}{1000}$$

k = 60.125

Ans: Option A

$$\frac{k}{60125} = 0.001$$

Or, $$\frac{k}{60125} = \frac{1}{1000}$$

Or, $$k = \frac{60125}{1000}$$

Or, $$k = 60.125$$

So, the units digit of k is 0

Hence, answer will be (A) 0
