Question

fast plz ........ tomorrow is my paper

Answer 1

Solution -

Given data -

Simple Interest [SI] = ₹ 500

Principal [P] = ₹ 4,000

Rate [R] = 5 % p.a.

Here, we have to find the require time

We know,

Time = SI × 100/P × T

∴ Require time

= [ 500 × 100/4,000 × 5 ] Years

= [ 100/40 ] Years

= [ 5/2 ] Years

= 2.5 Years

∴ Require time is 2.5 Years

Answer 2

Find interest for 1 year:

interest = 5% x Rs 4000 = 0.05 x 4000 = Rs 200

Find the amount of time needed to earn Rs 500:

Rs 200 = 1 years

Rs 1 = 1/200 year

Rs 500 = 1/200 x 500 = 2.5 years

Answer: It will take 2.5 years to earn Rs 500 interest at 5%
