I understand the provided solution but anyway I am curious what am I doing wrong here:

$$R=40 \frac{km}{h}=\frac{100}{9} \frac{m}{s}$$

$$T=3 s$$

$$D=75 m$$

Speed of the oncoming train in meters per second = N
Solution:

$$(\frac{100}{9}+N)*3=75$$

$$\frac{100}{9}+N=25$$

$$N=25-\frac{100}{9}$$

$$N=LT15\frac{m}{s}=LT54 \frac{km}{h}$$

So I am picking the B. Where is the bug?
