Download Solution PDFGiven:
Current height of tree = 9 feet
Every year it grows = 1/9th of its height
Time = 3 years
Formula used:
Height after n years = Initial height × (1 + growth rate)n
Calculation:
Growth rate = 1/9
Height after 3 years = 9 × (1 + 1/9)3
⇒ Height after 3 years = 9 × (10/9)3
⇒ Height after 3 years = 9 × (1000/729)
⇒ Height after 3 years = 9 × 1.371
⇒ Height after 3 years = 12.34 feet
∴ The correct answer is option (2).
