If the difference between the compound interest compounded half yearly and the simple interest
certain sum of money at the rate of 19 % per annum for one year is 72, then the sum is:
(A) 10000 (B) 15000
(C) 20000 (D) 25000
(E) None of these​

Answer 1

CI =P (I +9.5/100) 2-P

= I. I99025P-P

SI=px 1x19 / 100 = 0.19 P

Cl-SI=1.199025 P-P-0.19 p = 72

P=72/0.009025=7988

SUM=Rs7988
