Question

if a certain principal amounts to ₹44000 at 5% p. a. over 2 years, how much will it amount to in 3 years at the same rate? solve it with steps please the answer is 46, 000

Answer 1

If the Principal is x
Simple Interest = ( Principal X Time X Rate ) / 100
                         = ( x X 2 X 5 ) / 100
                         = x/10
Principal           = Amount - Simple Interest 
                   x    = 44000 - x/10
              x X 10 = 44000 - x
            10x + x = 44000
                   11x = 44000
                      x = 44000/11
                      x = 4000     
Simple Interest = ( Principal X Time X Rate ) / 100
                         = ( 4000 X 3 X 5 ) / 100
                         = 60000/ 100
                         = 600
Amount             = Principal + Interest
                         =  4000 + 600
                         = 4600

Answer 2

Answer:

Let the principle be Rs P.

Give, r = 5, n = 2 and A = Rs. 44000.

We know that, A = P + S.I.

∴ Rs. 44000 = Rs P +

⇒ Rs P + Rs= Rs 44000

Thus, the principal is Rs 40000.

Amount at the end of 3 years

= P + S.I.

= Rs 40000 +

= Rs 40000 + Rs 6000

= Rs 46000.

Thus, the amount at the end of 3 years is Rs 46000
