Answer 1

Step-by-step explanation:

i) interest paid = final amount - principal amount

= 16320-12000 = 4320

ii) I = PRT/100

R = Rate of interest = 100I/PT

R = (100 x 4320)/(12000 x 3)

R = 12% per annum

iii) Prem's rate of interest is same as Geeta's = 12% p.a.

iv) I = PRT/100

P = 12000, R = 12, T = 5

I = (12000 x 12 x 5) / 100

I = 7200

v) Total = Principal + Interest

Total = 12000 + 7200 = 19200
