Answered by hazelgarg1601

Compound Interest - Simple Interest= ₹620
At:
Rate= 10%
Time= 3 years
Principle = x

S.I = P*R*T/100
= X*10*3
=30x

C.I= X*10*1= 10x
= x+10x *10= 10x+100x
= 10x+100x*10= 100x+1000x

According to question :
1100x-30x = 620
1070x=620
X= 620/1070
X= 0.57943925

Principle = 0.57943925
