Correct Answer - Option 3 : 112.50
Given:
First case:
P = Rs. 5000, R = 4%, T= 2 years
Second case:
P = Rs 5000, R = 25/4 %,T = 2 years
Formula used:
S.I = (P × R × T)/100
Where, S.I = Simple interest, R = Rate %, T = Time
Calculation:
Interest paid by Sachin = (5000 × 4 × 2)/100 = Rs. 400
Interest recieved by Sachin = (5000 × 25/4 × 2)/100 = Rs. 225
His gain for two years = Rs. 625 − Rs. 400 = Rs. 225
His gain per two years = Rs. 225/2 = Rs. 112.50
∴ The gain of one year by Sachin is Rs. 112.50
