$\textbf {Hey there, here is the solution.}$

.............................................................................................

A = P( 1 + RT)

Given A = Rs 900, R = 10%, Time = 8,

900 = P( 1 + (0.1)(8) )

900 = P(1 + 0.8)

900 = 1.8P

P = 900 ÷ 1.8

P = Rs 500

Answer: The principal amount is Rs 500
