pls mark brainliest

Step-by-step explanation:

Interest rate is 15% per annum so 7.5% for half year

We get two times interest in one year so total interest is

7.5+ 7.5 + (7.5*7.5)/100 = 15.5625

So

16000* 15.5625/100= 2490rs ans

Answer 2

Answer:

A = P(1+r/200)^2n, P = 16000, n = 1 , r= 15%

A = 16000(1+15/200)^(2×1)

=> 16000 ( 1+3/40)²

=> 16000 ( 43/40)²

=> (16000 × 43 × 43)/(40×40)

=> 10×43×43

=> Rs 18,490

A = 18,490

I = A - P

=> 18490 - 16000

=> Rs 2,490

therefore A = 18490 and C.I = Rs 2,490
