Question

If Rs.4‚00‚000 amount Rs.5‚92‚000 in 4 years, find the rate of interest.​

Answer 1

Answer:

12.

Step-by-step explanation:

P = 400000

A = 592 000

SI = A - P

SI = 592000 - 400000

SI = 192000

r = si × 100/ P×T

r = 192000 ×100 / 400000× 4

on solving, we get

r = 12%p.a

Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find the rate of Interest.
• So, to find that, we have to use the formula of :

⇒ Rate = (100 × Interest)/(Principal × Time)

Given :

• Principal = Rs. 4,00,000
• Simple Interest =
• Time = 4 years

To find :

• the rate of interest

Solution :

⇒ Let's find the Simple Interest.

Simple Interest = 592000 - 400000

                         = 192000

Simple Interest = P × R × T/100

           192000 = 400000 × R × 4/100

Rate = (100 × Interest)/(Principal × Time)

        =  (100 × 192000)/(4‚00‚000 × 4)

        = 19200000/1600000

        = 12%

Therefore, the Rate of Interest is 12% per annum.
