Question

please answer this question ​

Answer 1

Step-by-step explanation:

r1 = 10

R2 = 5

S = 200

S = {1-(r1/100)}{1-(r2/100)}C

200 = {1-(1/10)}{1-(1/20)}C

200 = (9/10)(19/20)C

200 = (171/200)C

C = (200 × 200)/171

C = 40000/171

C = 233.92

Answer 2

Answer:

c is equal to 233.92

hope that u are fine
