y represents younger brother, o represents older brother, s represents sister, m represents mother, f represents father, i represents you
.
i%2By=16
13%2By=16
y=16-13
y=3
age of younger brother is 3
.
y%2Bo=17
3%2Bo=17
o=17-3
o=14
age of older brother is 14
.
s=y%2B15
s=3%2B15
s=18
age of sister is 18
.
m=s%2B19
m=18%2B19
m=37
age of mother is 37
.
d=m%2B2
d=37%2B2
d=39
age of father is 39
