Vasudevan invested Rs. 60,000 at an interest rate of 12%

i) A = p(1 + r/200)^(2n), when compounded half-yearly
n = 6 months = 1/2 year
= 60000(1 + 12/200)^(2 x 1/2)
= 60000(1.06)
= Rs. 63600
Amount after 6 months = Rs. 63,600
ii) A = p(1 + r/200)^(2n)
n = 1 year
= 60000(1 + 12/200)^(2 x 1)
= 60000(1.1236)
= Rs. 67416
Amount after 1 year = Rs. 67,416
