Question

At what time the sum Rs. 5000 will be doubled at the interest
of 10% per annum?​

Answer 1

Time=
`10` years

Explanation:

Let total time
`=t`

Initial Amount
`=5000`

Final Amount
`=10000`

Total interest = Final Amount - Initial Amount

`=10000-5000\\=5000`

Simple Interest
`=(Initial Amount* time* rate)/(100) \\\\5000=(5000* t * 10)/(100)\\(t)/(10) =1\\t=10 \ years`
