Question

In a family of $3$ members, father is $20$ cm taller than his wife, wife is $15$ cm shorter than their son, and son's height is $1$ m $75$ cm. What is the height of the father? How tall is the mother?

Answer 1

Step 1: Finding the height of the mother.

Given: Son's height $=1$ m $75$ cm.

$=175\mathrm{cm}$ [$1\mathrm{m}=100\mathrm{cm}$]

And mother is $15$ cm shorter than her son.

So, mother's height is$=175-15$

$=160\mathrm{cm}$

Step 2: Finding the height of the father.

Father is $20$ cm taller than his wife.

So, father's height $=160+20$

$=180\mathrm{cm}$

Hence, height of father is $180\mathrm{cm}$ or $1\mathrm{m}80\mathrm{cm}$ and mother is $160\mathrm{cm}$ or $1\mathrm{m}60\mathrm{cm}$.
