Verified Hint: - Here we go through by the formula of simple interest that we study in the chapter of simple interest. i.e.$SI = \dfrac{{P \times R \times T}}{{100}}$ . By this formula we will be able to calculate the rate. Complete step-by-step answer: Here in the question the principal amount is not given. Note: - Whenever we face such a type of question, the key concept for solving the question is to first assume the principal amount because the principal amount is not given and then proceed with the question to find the S.I. Then by putting the formula of S.I we will get the terms which we need to find. Uh-Oh! That’s all you get for now. We would love to personalise your learning journey. Sign Up to explore more.

So, the Amount received after 20 years = ₹ 200. (adsbygoogle = window.adsbygoogle || []).push({}); We know that, Principal + Interest = Amount. Hence, Interest = Amount - Principal = ₹ (200-100) = ₹ 100. The Simple Interest earned on a sum of ₹ P for a period of T years at the rate of R% p.a S.I is given by P× R×T100. So, ₹ 100 = 100×R× 20100 Hence, R = 5%.Solve Textbooks Question Papers At what rate Percent of simple interest will a sum of money double itself in 12 years * 6 years 2 months 8 years 4 months 4 years 4 months 8 years 2 months?"At what rate percent of simple interest will a sum of money double itself in 12 years?`8 1/4%` - YouTube.
How many years will a sum of money doubles itself at 12 per annum?In this problem, it is given that the rate is 12 % per annum and we need to find the time in which the principal amount doubles. The total amount at the end of N years is the sum of simple interest and the principal amount. Hence, the required time is 8 years and 4 months.
At what rate percent per annum will a sum of money double in 12.5 years?5% per annum rate of interest.
At what rate percent will a sum double itself in 10 years?Hence the required rate in which the sum becomes double itself in 10 years is 10%.
