Question

the compound interest calculated yearly on a certain sum of money for a second year is rupees 1089 and for the third year it is rupees 1197.90 calculate the rate of interest and the sum of money

Answer 1

hey!

here is your answer =>

Answer: 9900

Explanation:given C. I for 2nd yr =1089

C. I for 3rd yr = 1197.90

Now difference between two C. I =1197.90-1089=1089.90

Now R%=100×108.90÷1089×100=10%

Then let P =x

SI= x ×10 ×1 ÷100=x÷10

Amt= 11x÷10

P for 2nd yr =11x÷10

SI= 11x ÷100

We know that SI= CI

Given that

11x÷100=1089

x= 1089×100÷11=9900

Therefore total sum is 9900
