A Find the amount compounded annually on Rs 25,000 for 2 years if the rates of interest for two years ore 10 % and 12 % respectively,

Amount = Rs. 30250 when Rate = 10%

Amount = Rs. 31360 when Rate = 12%

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;

Amount = Rs. 30250 when Rate = 10%

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;

Amount = Rs. 31360 when Rate = 12%

to determine the unit cost your would divide the total cost by the number sold.
