Question

The height of a plant is 80 cm and it is expected to grow at the rate of 20% every month. What will be the plant's height at the end of 3 months? (Calculate Using Compound Interest Formula.)

Answer 1

In this sum, amount is the height of plant at the end of 3 months Time period(n) = 3 months Principal (P) = 80cm We know, A= P(1+ r/100)power n =) A= 80(1+ 20/100)power 3 =) A= 80 X 120/100 X 120/100 X 120/100 =) A= 13824/100 =) A= 138.24 = 138 (approximately) So the height of the tree at the end of 3 months = 138 cm Please mark my answer as brainliest. Thank You!
