INTREST = PTR÷100
A) 3,10,800×3×12÷100
=111888
Intrest+amount
=310800+111888=422688.
B) 18000×22×10÷100
= 39600
Total =18000+39600
=57600
C) 762500×12×8÷100
= 732000
Total=762500+732000
=1494500
D)1tear is equal to 12months
8000×12×9÷100
= 8640
Total=8000+8640
= 16640.
E) 10000×12×8÷100
= 9600
Total= 10000+9600
=19600.
