Step-by-step explanation:
a. let the present age of son be x
present age of father = 2x-10
sum of present ages of father and son=107
a.t.q
x+2x-10=107
x+2x-10=107
b. present age of son =x
x+2x-10=107
3x=107+10
x=117/3
x=39
.. present age of son is 39years.
c. present age of son=39yrs
age after 8yrs=39+8
=47yrs.
present age of father=2x-10
=(2*39)-10
=68
