Question

A sum of money amount to rs 9800 after 5 years and rs 12005 after 8 years same rate of simple interest

Answer 1

Answer:12%

Step-by-step explanation:

A sum of money amounts to 9800 after 5 years and 12005 after 8 years at the same rate of simple interest.

Interest for 3 years = 12005-9800= 2205

Interest for 1 year = 2205/3 = Rs. 735

Int for 5 yrs = Rs. 3675

Principal = 9800-3675 = Rs. 6125

Rate of interest = 735*100/6125 = 12 %
