Amount at the end of 1 year=Principal+Interest
Interest=
100
PRT
=
24000×1×10
=Rs.2400
∴Amount at the end of 1 year=24000+2400=Rs.26400
Interest for the 2 year=
26400×10×1
=Rs.2640
Amount at the end of 2 year=26400+2640=Rs.29040
Let he return Rs.x at the end of first year
∴29040−x=12540
⇒x=29040−12540
⇒x=Rs.15000
