​

Answer 1

Step-by-step explanation:

P = A - SI

given

p = ?

r = 5%

t = 2,3 & 4

A = ₹1725

si = p r t /100 (for 2 years)

1725 = p * 5/100 * 2

p = 1725 * 100 / 5 * 2

p = ₹17250

(for 3 years )

1725 = p * 5/100 * 3

p = 1725 * 100/5 * 3

p= ₹11500

(for 4 years )

1725 = p * 5/100 * 4

p = 1725 * 100/ 5 * 4

p = ₹8625
