if someone will give correct answer of own I'll follow them​

Answer 1

Answer:

Given :-

Rate = 4%

To Find :-

After how many years it will doubled

Solution :-

We know that

SI = PRT/100

Let

P = x

SI = x

R = 4%

T = t

A = 2x

x = x \times× 4 \times× t/100

100x = 4tx

Cancelling x

100 = 4t

100/4 = t

25 = t

{\textsf{\textbf{\underline{Time is 25 years}}}

Answer 2

Answer:

here is your answer

Step-by-step explanation:

Let sum = x

Then, amount = 2x

∴ S.l.=x

∴ Time =

Sum×Rate

100×S.I.

=(

x×4

100×x

)years = 25 years
