Calculate the amount of rupees 31250 at the end of 2½ years, compounded annually at 8% per annum.​

Principal = 31250

Time= 2 and 1/2 years

Rate= 8% so first we take out the amount for 2 years which would be: 36450

Now we we will take out the amount for 1/2 years. Now the rate for 1/2 years is 4% with principal

The amount for 1/2 years for 4% rate is= 37908

37908 is the amount after 2 and 1/2 years at the rate of 8%

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
