Question

1. If SI = Rs 680, time period is 2 years, rate of interest = 8%, then principal =_____​

Answer 1

SI=principal × rate × time

680=p×8%×2

680=px0.08×2

680=.16P

680/.16=0.16/.016P

P=4250

Answer 2

Answer:

SI = p into r into t / 100

Let the P be x

680 = x into 8 into 2 / 100

680= x into 4 /25

680 into 25 /4 = x

4250 = x

Principal = 425o
