as we know that formula of simple

interest is P*R*T/100

S.I. = P★R★T / 100

S.I. = 450rs. * 4 * 3/100

S.I. = 5400 rs/100

S.I.= 5400 rs

Answer 2

GIVEN

Principle=450 Rs

Rate of Interest=4%

Time= 3 years

TO FIND

Simple Interest= PTR÷100

SOLUTION

We can solve the problem by this mathematical formula,

S.I= PTR÷100

i.e,

   S.I=[450×3×4]÷100

       =5400÷100

        =54

So.the simple interest at the end of the year is Rs 54.
