Question

A sum of money put at 9 percent per annum simple intrest accounts to rupees 1016 in 3 years. What will amount to in 2 years at 8 percent per annum.​

Answer 1

Find the interest percentage earned in 3 years:

1 year = 9%

3 years = 9 x 3 = 27%

Find the principal amount:

Interest = 27%

Percentage of money with interest = 100 + 27 = 127%

Sum of money with interest = Rs 10160

127% = rs 10160

1% = 10160 ÷ 127 = Rs 80

100 = Rs 80 x 100 = Rs 8000

Find the interest for 2 years at 8% per annum:

1 year = 8% x 8000 = 0.08 x 8000 = Rs 640

2 years = 640 x 2 = Rs 1280

Find the amount after 2 years:

Total amount = Rs 1280 + Rs8000 = Rs 9280

Answer: The amount is Rs 9280
