Question

If the rate of simple interest per annum be `6%`, then find the simple interest of `Rs 3500` from `5th` January `31st` March `1954`.

Answer 1

Here, total number days are as follows:

Now, `146` days `=(146)/(365)` years `=(2)/(5)` years
So, here principal, `p=Rs3500`
rate of interest, `r%=6%`
Time, `t=(2)/(5)` years
We know that `I=(prt)/(100)=Rs(3500xx6xx(2)/(5))/(100)=Rs84`
Hence the required simple interest `=Rs84`.
