Question

find principal amount if rate of interest is rs.20 and rate is 2 p.c.a. and time is 2 months

Answer 1

principal=x

rate=2 p.a.

time=2 months.

interest=₹20

simple interest=(p×r×t)/100

20=(p×2×2)/12×100

20×12×100=p×4

(20×12×100)/4=principal29

principal=₹6000

amount=principal+S.I.

amount=6000+20

amount=₹6020
