Question

A tree's height increase by 15%. If a tree is 23 feet high, how tall will it be in one year ?

Answer 1

Increased height:-

$\\ \sf\longmapsto 23\times 15\%$

$\\ \sf\longmapsto 23\times \dfrac{15}{100}$

$\\ \sf\longmapsto \dfrac{345}{100}$

$\\ \sf\longmapsto 3.45$

Now current height:-

$\\ \sf\longmapsto 23+3.45=26.45ft$
