Question

if Rs 3500 yields a simple interest of Rs 1625 after 3years , what amount will we get from Rs 5200 after 2 years at the same rate of interest?

Answer 1

Answer 2

Rs 3500 yields interest.
So, Principle = Rs 3500
Interest = Rs 1625
Time = 3 years
Let the rate of interest = r%
We know Interest = principle*time*rate of interest/100
Therefore
1625 = 3500*3*r/100
1625 = 105r
r = 1625/105
r = 15.48 % (nearly)

Now, rate of interest is same
Principle = Rs 5200
Time = 2 years
Interest = Principle*time*rate of interest/100
             = 5200*2*15.48/100
             = 1609.92
Amount = principle + interest
             = 5200 + 1609.92
             = Rs 6809.92
  
The amount we get = Rs 6809.92

Hope this helps you.
