Question

If Tanvi gives an interest of Rs 40 for one
year at 5% rate p.a. What is the sum she
has borrowed? ?​

Answer 1

Step-by-step explanation:

She has borrowed Rs 800.

Step-by-step explanation:

Given that:

Time = 1 years

Rate of interest = 5% per annum

Simple Interest = Rs 40

To Find:

What is the sum she has borrowed?

Formula used:

SI = (P × R × T)/100

Where,

SI = Simple interest

P = Principal/Sum

R = Rate of interest

T = Time

Finding the sum:

⟶ SI = (P × R × T)/100

Substituting the values.

⟶ 40 = (P × 5 × 1)/100

⟶ 40 = 5P/100

⟶ 5P = 40 × 100

⟶ 5P = 4000

⟶ P = 4000/5

⟶ P = 800

∴ The Sum Tanvi has borrowed = Rs 800

hope this helps you!!
