Question

Riya is a 13 year old girl who is eager to know her height at maturity. She is presently $130cm$ tall and her corresponding full height is $95\%$. What do you think her height during maturity would be?

• A. She would be approximately $135cm$.
• B. She would be approximately $137cm$.
• C. She would be approximately $139cm$.
• D. She would be approximately $133cm$.

Answer 1

The correct option is B She would be approximately $137cm$.

The height of an adolescent at the time of maturity can be predicted using a formula:
$\frac{Presentheight\left(incm\right)}{\%offullheightpresently}\times 100$.
Hence,
$\frac{130cm}{95}\times 100$ is approximately $137cm$.
