Question

At what rate of interest will a sum of money double itself in 5 years.

Answer 1

Step-by-step explanation:

If a sum doubles itself in 5 years by simple interest. Calculations: Let P be the principal amount and R be the rate of interest. ∴ The rate of simple interest p.a. is 20%.

Answer 2

Answer:

If a sum doubles itself in 5 years by simple interest.

If a sum doubles itself in 5 years by simple interest.Time (T) = 5 years

If a sum doubles itself in 5 years by simple interest.Time (T) = 5 yearsFormula used:

If a sum doubles itself in 5 years by simple interest.Time (T) = 5 yearsFormula used:S.I. = (P × R × T)/100

If a sum doubles itself in 5 years by simple interest.Time (T) = 5 yearsFormula used:S.I. = (P × R × T)/100Where,
