Question

In what time will principal of ₹3200 at the rate of 8% become ₹3840

Answer 1

Answer:

assuming simple interest.

P=3200Rs= principal

r=8% = rate per annum

A= 3840Rs= final amount

interest=A-P= 640Rs.

t= time= ?

.

formula,

interest= Px rx t/100

.

640= 3200x 8x t/100

.

t= 640x100/(3200×8)

t= 8000/3200 = 80/32

t=5/2= 2.5 years.

Answer 2

Answer:

A = P + SI

3840 = 3200 + SI

SI = 640

SI = P.R.T/100

640 = 3200.8.T/100

T = 100 / 40

T = 2.5 years
