Question

if the interest for 5years on rs 3000 is rs 525 find the interest on rs 2200 for 6years at the same rate of interest
​

Answer 1

Step-by-step explanation:

Here, SI= 525, PA=3000, Time=5years

so we can calculate rate r%=?

we know, SI=PTR/100

R=SI×100/ PT

525×100/3000×5 = 21/6

Again , PA=2200, Time=6 year ,

given same rate of interest ,so we will use the above rate of interest 21/6

now, SI= PTR/100

3000×6×21/6×100= 462
