Question

A man deposit rs 3200 at 5% interest per annum . in how many years will he earn a simple interest of rs 800?​

Answer 1

Answer:

5 years

Step-by-step explanation:

Principal amount  = Rs.3200

rate = 5% p/a

Simple interest for 1 year = Rs.3200 x 5/100

                                         =  Rs.160

Simple interest required =  Rs.800

Time x interest of 1 year = Rs.800

Time x Rs.160 = Rs.800

Time = Rs.800/Rs.160

Time = 5 Years
