Question

in how many years will a sum of money double itself at 18.75% p.a. simple interest ?​

Answer 1

Let The Principal be x

R = 18.75%

T = y

A = 2x --------as the money doubles itself

A = P + I

2x = x + x*18.75*y/100 -----------[I = PRT/100]

2x = x + 18.75xy/100

2x - x = 18.75xy/100

x = 18.75xy/100

100x = 18.75xy

100 = 18.75y ----------------[Dividing x on Both The Sides]

100/18.75 = y

y = 5.3333 Years

y = 5 1/3 Years

y = 5 Years 4 Months
