Find the amount which Ram will get on ₹ 4,096, if he gave it for 18 months at (12) ½ % per annum, interest being compounded half yearly.

Here, Principal (P) = ₹ 4096,
Rate of Interest (R) = (12)½ = 25/2% = 25/2% (compounded half yearly)
Time (n) = 18 months = 3/2 years = 3 half-years (compounded half yearly)
Amount (A) = P(1+R)ⁿ = 4096 (1+25/4×100)³ = 4096(1+1/4×4)³
= 4096(17/16)³ = 4096x 17/16 x 17/16 x 17/16 =₹ 4,913
