Father's years of birth = pqzy
We have
\(mn\div2=p+q+z+y\)
\(a\times10\div2+b\div2=p+q+z+y\)
\(a\times5=b\times2\)
\(\Rightarrow a=2;b=5\)
So father age is 25Father's age in 2019 is:
\(25\times2=50\left(ages\right)\)
Father year of birth is :
\(2019-50=1969\left(years\right)\)
So year of birth is 1969
