Answer 2

$\huge \bigstar \mathtt { \underline{ \red{A}{ \pink{n}{ \green{s}{ \purple{w}{ \blue{e}{ \orange{r}}}}}}}}$

• $\sf { \red{let \: grand \: daughter’s \: age \: be \: = x}}$

As per question

Grandfather’s age ≈ Grand daughter's age+54

• ${ \blue{10x = x + 54}}$
• $\green{9x = 54}$
• $\orange{x = 6}$

Grand daughter’s age = 6 year.
