Answer:
46
Step-by-step explanation:
Let the son's & Fathers age be " X " & " Y " respectively.
X + 28 = Y ( when born )
X + Y = 44 ( In 2010)
from eq. 1 we get,
X + X + 28 = 44
2X = 16
X = 8
Y = 8 + 28
Y = 36
The son's age is 8 & the dad's age is 36 years in 2010.
Thus for 2020 the son's age is 18 ( 8+10 ) & dad's age is 46 ( 36+10) years.
