Question
If a sum on compound interest becomes 13 times in 9 years, then with the same interest rate, the sum will become 169 times in how many years?Choose the best optionClear Response18201610
Solution
The problem is based on the concept of compound interest in mathematics.
Given that a sum becomes 13 times in 9 years, this implies that the sum is squared (since 13*13 = 169) in double the time.
Therefore, the sum will become 169 times in 2*9 = 18 years.
So, the correct option is 18.
