Question

In what time will Rs. 3,600 amount to Rs. 4,410 at 9% per annum simple interest?​

Answer 1

Answer:

GIVEN, A= 4410

P= 3600

R= 9%

let the required time be t

$a = p + \frac{prt}{100} \\ 4410 = 3600 + \frac{3600 \times 9 \times t}{100} \\ 4410 - 3600 = 36 \times 9 \times t \\ t = \frac{810}{36 \times 9} \\ t = 2.5$

Hence 3600 will become 4410 at 9%PA in 2.5 years.
