Answer:

Step-by-step explanation:

Given, amount, A = ₹ 13924

time period , n = 2

interest rate , r = 18 % per annum

Let principal is P

use formula,

so, 13924 = P(1 + 18/100)²

=> 13924 = P(118/100)²

=> P = 13924 × 10000/118 × 118

P = 10,000

hence, principal is ₹ 10, 000

Answer:

Step-by-step explanation:

amount = 13924

I = PRT/100

= I = P * 18 * 2 /100

= I = 36P/100

= I = 9P/20

9P/20 + P = 13924

= 29 P = 278480

= P = 9602.75
