Step-by-step explanation:

use algebra

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
