An amount doubles itself in 5 years with simple interest. what is the rate of interest
Show
Solution The correct option is A 20Time period = 5 years Let the principal = P Simple interest rate = R% p.a. Pricipal doubles in 5 years, so amount after 5 years will be 2P. Simple interest = Amount - Principal Simple interest = 2P - P = P Simple interest = PRT100 P = P×R×5100 R = 20%Question At what percent by simple interest will a sum of money double itself in 5 years 4 months?Hint: Use the formula of total amount and then find the rate of interest R.The correct answer is: 18.75%Complete step by step solution:Formula for total amount = A = P + SI…(i)where A is the total amount, P is the principal amount and SI is simple interest .Here, A = 2P and SI = where P is Principal amount, T is number of years and R is the rate of interest.We have, T = 5 years and 4 months = years (given) and R = ?On substituting the known values in (i), we have .Subtract P from both sides.Then we have, So, we have R = 18.75%At 18.75% per annum the sum amount will double itself in 5 years and 4 months.Book A Free DemoMobile* +91 I agree to get WhatsApp notifications & Marketing updates Related Questions to studyMaths- A sum of money lent out at simple interest amounts to Rs. 1240 in 4 years and Rs 1360 in 6 years.

Step 1 of 1: In what time will a sum of money doubles itself at 5% simple interest?Answer. time = si × 100 / R × P 100× 100 / 5 × 100 = 20 years .
At what rate of simple interest will an amount double itself?Amount=2x. As we know the simple interest means principle amount subtracted from final amount i.e. Hence the required rate in which the sum becomes double itself in 10 years is 10%.
At what rate of simple interest will an amount doubles itself in 3 years?∴R=25.99% per annum. Q. A sum amounts to Rs.
What is the rate of interest PCPA an amount doubles itself in 6 years?Thus, the rate of interest percent compounded per annum is 20.
