Question

If some of a money double it itself in 20 years. In how many time will be in simple interest same rte of itself of triple. from class 8

Answer 1

Answer:

40 yrs.

Step-by-step explanation:

Let the sum of money be X

SI=Amount-Principal

In this case, Simple Interest is = X

SI=P*R*T/100

X=X*R*20/100

100x/20x=R

5%=R

Now the X is tripled,

In this case SI=3x-x=2x

SI=P*R*T/100

2x=X*5*T/100

2x/X=T*1/20

2*20=T

40=T

So it will take 40 years to make the sum of money tripled.
