chandana mahapatra  (10 years ago)

in simple words S.I= PTR/100=(P*1*10)/100 P/10
HERE AMOUNT A= p+ S.I= P+ P/10=11P/10....
NOW FOR COMPOUND INTEREST WHEN CALCULATED HALF YEARLY AMOUNT=P[1+R/200]^2T=P[1+10/200]^2*1=441P/400

here its given in the question dat diff btwn simple interest and compound interest half yearly ... is 25


=> 441p/400-11p/10= 25 =>p/400=25 =>p= 400*25=10000 so sum = 10000

since CI-SI=25
p{(1+5/100)^2 - 1}-P*10*t/100=25

p=10000
