Question

Principal =rs.5000, time = 3 year's, rate = 12%p.a

Answer 1

Principal Amount= P =5000

Time = n = 3 years

Rate of interest Per Annum = i = 12%p.a

Compounded Amount = P(1+i)^n

= 5000(1 + 12/100)^3

=5000(1 + 0.12)^3

=5000(1.12)^3

=5000(1.404928)

=7024.64

Answer 2

solution S.I.=Principal × Rate % Time / 100 , S.I. = 5000×12 ×3 /100 , cut 00of 100 to 5000 , then 50×12×3=Rs.1800 ,. Amount= Principal + S.I. , 5000 + 1800=6800
