Answer:
Amount = Rs. 30250 when Rate = 10%
<em>Amount = Rs. 31360 when Rate = 12%</em>
Step-by-step explanation:
Given




Number of times (n) = Annually

Required
Determine the Amount for both Rates
Amount (A) is calculated by:

When Rate = 10%, we have:
Substitute 25,000 for P; 2 for t; 1 for n and 10% for r



Convert 10% to decimal




Hence;
<em>Amount = Rs. 30250 when Rate = 10%</em>
When Rate = 12%, we have:
Substitute 25,000 for P; 2 for t; 1 for n and 10% for r



Convert 12% to decimal




Hence;
<em>Amount = Rs. 31360 when Rate = 12%</em>
