Question

*What will be the principal of amount Rs.480 for 3 years at the rate of 3 PCPA?* 1️⃣ ₹ 1200 2️⃣ ₹ 2400 3️⃣ ₹ 2000 4️⃣ ₹4800​

Answer 1

Given: Amount (A)= Rs.480

           Time (t)= 3 years

            Rate(r)= 3 PCPA  ($\frac{3}{100} = 0.03$)

To Find: Principal value (P)

Solution: A=P(1+rt)

                P=$\frac{A}{1+rt}$

                P=$\frac{480}{1+0.03*3}$

                P=$\frac{480}{1+0.09}$

                 P=$\frac{480}{1.09}$

                 P=440.3669
