Question

At a certain rate of simple interest a certain sum doubles itself in 10 years it will become tremble in

Answer 1

Answer:

in 20 year it will be triple

Answer 2

It will become triple in 20 years.

Step-by-step explanation:

Since we have given that

Amount get double in 10 years.

so, A = 2P

So, Amount = Sum + Interest

$2P=P+I\\\\2P-P=I\\\\P=I$

So, it becomes,

$P=\dfrac{P\times R\times 10}{100}\\\\R=10\%$

Now, If amount gets triple, it becomes,

Amount = Sum + Interest

3P  = P + interest

Interest = 3P-P = 2P

So, it becomes,

$2P=\dfrac{P\times 10\times t}{100}\\\\2\times 10=t\\\\20=t$

Hence, it will become triple in 20 years.
