Family Ages Calculation

I have 4 brothers. Mom was 22 years old when the oldest, Marcus, was born. Walter is a year younger than him. There is a 3-year difference between Walter and Ivan. Hugo was born 3 years before Ivan, and he is 2 years older than me; he is now 12 years old. How old is Mom now?

Final Answer:

M =  35

Step-by-step explanation:

$$\begin{gathered} H=12 \\ J=H-2=12-2=10 \\ I=H-3=12-3=9 \\ V=I+3=9+3=12 \\ {M}_1=V+1=12+1=13 \\ M=22+M_1=22+13=35 \end{gathered}$$
