Question

If difference between C.I and s.i ₹21 with 5%annual rate in 2 years find the principale?​

Answer 1

Explanation:

formula used=(PR^2)/100^2=D

where P=principal

R is rate

D is difference between CI and SI

so( P*5*5)/(100*100) =21

P*25/10000=21

P=(21*10000) /25

P=8400

So 8400 is the Principal
