Answer 1

Step-by-step explanation:

A=Rs. 5320

P=Rs. 4800

T=3years

I=5320-4800=Rs. 520

R=(520x100)/(4800x3)

=3.61%

Answer 2

Answer:

3.61%

Step-by-step explanation:

Principal = ₹4800

Amount = ₹5320

Time = 3 years

Simple Interest = Amount - Principal

                         = ₹5320 - ₹4800

                         = ₹520

Rate = (Simple Interest * 100)/(Time * Principal)

        = (520 * 100)/(3 * 4800)

        = 52000/14400

       = 3.61%
