Answer 1

(1)

We know that CI = P(1 + r/100)^n - P

Given that r = 8%, n = 2 years, CI = 2496.

= > 2496 = P(1 + 8/100)^2 - P

= > 2496 = P(108/100)^2 - P

= > 2496 = P(27/25)^2 - P

= > 2496 = P(729/625) - P

= > 2496 * 625 = 729P - 625P

= > 1560000 = 104P

= > P = 1560000/104

= > P = 15000.

We know that SI = PTR/100

= 15000 * 3 * 8/100

= 3600.

Therefore the simple interest = 3600.

(3)

Given Principal = 10000, R = 8%, Time = n/2 years, 11248.64

We know that A = P(1 + r/100)^n

= > 11248.64 = 10000(1 + 4/100)^n

= > 11248.64/10000 = (104/100)^n

= > (104/100)^3 = (104/100)^n

= > n = 3.

Therefore the time = n/2 years

= 3/2

= 1 (1/2) years.

Hope this helps!
