Question

2. Find the amount and C.I. if the interest is compounded quarterly.
(c) Principal = 28000, Rate = 12% per annum = Time 9 months
(d) Principal = * 10,000, Time = 6 months Rate = 10% per annum​

Answer 1

Answer:

(a)28000×(1+12/4/100)9×4/12

28000×(103/100)³

28000×103/100×103/100×103/100

amount=30596.356

CI = 2596.356

(b) 10000(1+10/4/100)6×4/12

10000(1+1/40)²

10000(41/40)(41/40)

16810000/1600

amount=10506.25

CI =10506.25-10000=506.25
