Amount=P(1+R/100)^T=10240(1+25/2×100)^3
=10240(200+25/200)^3
=10240×225/200×225/200×225/200
=10240×9/8×9/8×9/8
=1280×9×9/8×9/8
=20×9×9×9
=20×729
=14580
Compound interest = 14580-10240=₹4340
=10240(200+25/200)^3
=10240×225/200×225/200×225/200
=10240×9/8×9/8×9/8
=1280×9×9/8×9/8
=20×9×9×9
=20×729
=14580
Compound interest = 14580-10240=₹4340

In compund interest
A=P(1+R/100)^t
P = 10240, R = 12½ = 25/2, T = 3 years.
A = 10240(1+25/200)³
= 10240(1+1/8)³
=10240(9/8)³
=10240×9/8×9/8×9/8
=1280×9/1×9/8×9/8
=160×9×9×9/8
=20×9×9×9
Amount = ₹ 14580
