After being dropped, a certain ball always bounces back to 2/5 of the height of its previous bounce. After the first bounce it reaches a height of 125 inches. How high (in inches) will it reach after its fourth bounce?

After being dropped, a certain ball always bounces back to 2/5 of the height of its previous bounce. After the first bounce it reaches a height of 125 inches. How high (in inches) will it reach after its fourth bounce? Correct Answer 8

Hints: প্রতিটি Bounce এ আগের height এর 2/5 অংশে চলে আসে। এখানে প্রথমে Bounce এর পরের height বলা। 4th bunce পরে height = 125× (2/5)3 = 8
