Given : At a certain rate of simple interest Rs 4050 amounts to Rs 4576.50 in 2 years .
Let rate of simple interest = r , Principle amount = P = 4050 , Time ( In years ) = t = 2 years
We know simple interest = P × r × t100 , Then we get
4050 + 4050 × r ×2100 = 4576.50⇒4050 × r 50 =526.5⇒81 r =526.5⇒r =526.581⇒r =6.5 %
Therefore,
At same rate 1 lakh amount to in 3 years will became = 100000 +100000 × 6.5 × 3100 = 100000 +1000 × 6.5 × 3 = 100000 + 19500 =Rs.119500 ( Ans )
