Question

what sum will amount to ₹ 6,600 in 4 years at 8% per annum simple interest ?​

Answer 1

⠀⠀⠀⠀Let the principal be x Rs.

⠀⠀⠀⠀Amount= 6600Rs.

⠀⠀⠀⠀Rate of interest= 8%.

⠀⠀⠀⠀Time= 4years.

⠀⠀⠀⠀S.I=Amount - principal.

⠀⠀⠀⠀(P*R*T)/100= 6600-x.

⠀⠀⠀⠀(x*8*4)/100=6600-x.

⠀⠀⠀⠀32x=(6600-x)100.

⠀⠀⠀⠀32x= 660000- 100x.

⠀⠀⠀⠀100x+32x=660000.

⠀⠀⠀⠀132x=660000.

⠀⠀⠀⠀x=660000/132.

⠀⠀⠀⠀x= 5000Rs.

⠀So Principal= 5000Rs.
