Answer 1

Answer:

60.9681

Step-by-step explanation:

Note

• SI = PTR

100

• CI = P( 1 + r) ^ n

In the given case

SI = P (2) (10)

100

SI = 20 × P

100

SI = P/5

CI = P ( 1 + 0.1 ) ^ 2

CI = P ( 1.01 ) ^ 2

CI = P ( 1.0201 )

As given

CI - SI = 50

[P ( 1.0201 )] - P/5 = 50

P ( 5.1005 ) - P = 50

5

5.1005P - P = 50 × 5

4.1005P = 250

P = 250/4.1005

P = 60.9681
