Answer 1

Step-by-step explanation:

1. Principal (P) = Rs. 500

   Interest (I) = Rs. 40

   Amount (A) = P + I

   Amount = 500 + 40

   Amount = Rs. 540

2. Interest = Rs. 130

   Amount = Rs. 680

   Principal = A - I

   Principal = 680 - 130

   Principal = Rs. 550

3. Principal = Rs. 43

   Amount = Rs. 60

   Interest = A - P

   Interest = 60 - 43

  Interest = Rs. 17
