Step-by-step explanation:
<h3>use algebra</h3>
onyango= 3a
daughter= let it be a
son= he is 4 times less than his father, 3/4a
8years
8+3a+a+8+3/4a+a
a+8+3/4a+a
7/4+1 = 8/4a+8 + 12y 20= 8/4a = 40years is the father 8 years later, so his present age is 40-8
32y= father now
daughter= 1/3×32=10years
son= 1/4×32= 8yrs
add 32+10+8= 50years
