Question

A sum of money put at 9% per annum simple interest amounts to 10160 in 3 years. What will it amount to in 2 years at 8% per annum?​

Answer 1

Step-by-step explanation:

1 year = 9%

3 years = 9×3 = 27%

percentage of money with interest = ₹ 10160

127% = 10160

1% = 10160/127 = ₹80

100 = ₹80×100 =₹8000

Interest for 2 years at 8% per annum:

1 year = 8% × 8000 = 0.08×8000 = ₹640

2 years = 640×2 = ₹1280

amount after 2 years:

total amount = ₹1280+₹8000 = ₹9280.

So, Answer = the amount is ₹9280
