Answer 1

Answer:

15000 $

Step-by-step explanation:

The sum is 15000 $.

Step-by-step explanation:

Px R x T/100 = PX [ 100 XR / 100] -1 = 216

PX 2 X 22/100- ([112/100] -1)

6P/2s (784 625 -625 /625 = 159 / 625) = 216

159 p - 150 p / 625 = 9p / 625 = 216 Thun the sum is 15000 $.

p = 216 x 625/9 = 15000 $

Answer 2

Answer:

15,000

Step-by-step explanation:

The difference between simple interest and compound interest for two years only=P(r/100)²---> This formula for only two years

We can directly apply the given values

Given Value

No.of years n=2yrs

S.I - C.I= rs.216

Rate of interest r=12%

S.I-C.I=P(r/100)²

216=P(12/100)²

216=P(3/25)²

216=P(9/625)

216×625=9P

135000=9P

P=135000/9

P=Rs.15,000
