Answer:
we use the formula
amount = p(1+r/100) (1+q/100)
here, r = rate for 1 year
and q=rate for 2nd year
A/q
amount =p(1+r/100) (1+q/100)
4452= p ( 1 + 6/100) (1+5/100)
4452= p (106/100) (105/100)
4452= 11130p/10000
4452*10000=11130p
44520000 =11130p
44520000/11130=p
4000=p
p=4000
so ,the principal is 4000
