Answer 1

Answer:

800

Step-by-step explanation :

Interest = p× r× t /100

40=P × 5× 1/ 100

P = 40 × 100 / 5

P= 800

Answer 2

Given:

If Tanvi gives an interest of Rs 40 for one year at 5% rate p.a.

To find:

what is the sum she has borrowed?

Solution:

Let the sum borrowed by Tanvi is P

Rate = 5%

Time is 1 year

Simple interest(I) = Rs 40

Finding the Principal:

I = PTR/100

=> 40 = Px1x5/100

=> 40 = 5P/100

=> 5P = 40x100

=> 5P = 4000

=> P = 4000/5

=> P = 800

Hence, the sum she has borrowed is Rs 800
