Question

In how many years asum of money will become double of itself at 10% p.a. at rate of simple interest

Answer 1

Answer:

answer is 10

Step-by-step explanation:

Let sum = x

amount 2x

SI = 2x-x = x

let Time = t

rate 10% p.a.

SI = P*R*T/100

x= x* 10* t/ 100

x= xt /10

10x= xt (by cross multiplication )

t= 10x/x

t= 10 years
