Answer 1

Step-by-step explanation:

Ok......

Answer 2

Think of ₹ P as a monthly in stallment

Duration (x) = 1 year = 12 months

We know that

Total monthly head = = × (x (x + 1)] / 2

Enter the value of x

= P × (12 × 13) / 2

With continuous calculation

= 78P

Interest = PRT / 100

Pricing

= (78P × 14 × 1) / (100 × 12)

So we get it

= 0.91P

So the maturity value = P × x + SI

6455 = P × 12 + 0.91P

6455 = 12.91P

With continuous calculation

P = 6455 / 12.91 = ₹ 500
