Answer 1

Given

shubham's age today $=12$ yrs

shubham father's age today $=42$ yrs

shubham's mother is 6 yrs younger then his

father

So, shubham mother's age today $=42-6$

= 36 yrs

1) Ratio of shubham's age today to his

mother's age today

$=\frac{12}{36}=\frac{1}{3}$

2) Ratio of shubham's mother's age today to his

father's age today

$=\frac{36}{42}=\frac{6}{7}$

3) when shubhm = 10, his mother $=36-2$

$=34$

Ratio $=\frac{10}{34}=\frac{5}{17}$
