In Example 13, the present age of the son is —

a $9$ years
b $10$ years
c $11$ years
d $12$ years

ব্যাখ্যা

Setting up the two age equations from Example 13 and solving them simultaneously eliminates one variable and yields the son's present age as $11$ years, which also satisfies both the original "sum" and "difference/ratio" conditions of the problem.
