Question

In what time will ₹3600 amount to 4410 at 9% per annum simple interest?

Answer 1

principle=3600Rs.

amount =4410

rate%=9%

time=?

SI= prt/100

si=(3600*9*t)/100

si=324t

since Amount =principle +si,

so, 4410=324t+3600

324t=4410-3600

324t=810

t=810/325

t=2.5 years

hope it helps you!!

Answer 2

Principal (P)= Rs. 3600

Amount (A)= Rs.4410

Rate of interest(R) = 9%

Time(T)= ?

Simple interest = A - P = 4410 - 3600 = Rs. 810

Simple Interest = PTR/100

810 = 3600 * T * 9/100

810 = 36 * 9 * T

810 = 324T

T = 810/324

T = 2.5

So Time = 2.5 years.
