Question

Find the amount and the C.I. on Rs.12,000 in
one year at 10% per annum compounded
half-yearly.​

Answer 1

Answer:

Principal (P) = ₹ 12,000

Rate (r) = 10%

Time (t) = 1 years

Amount = P × (1 +(r/ (2 × 100)) n × 2

= ₹ 12,000 × (1 + (10/200)) 2

= ₹ 12,000 × (210/200)2

= ₹12,000 × 21/20 × 21/20 = ₹ 13,230

C.I. = Amount – Principal

= ₹ 13230 - ₹ 12000 = ₹1230
