Question

rs4000 gives an interest rs720 at 9% . find the time period.


solve it......​

Answer 1

Let the time be T years.

SI = Rs. 720

P = Rs. 4000 , R = 9 %

SI = (PRT)/100

720 = (4000 × 9 × T )/100

T = 720/(40 ×9)

T = 2 years

Answer 2

Answer:

si = ₹720

p = ₹4000

r = 9%

si = (prt)/100

720 =(4000×9×t)/100

t =720/(40×9)

t = 2year
